How To Create An ETF Watchlist

[tonight]

I know this is not a ThinkScript question, but I was hoping someone here can help me.
How do I make an All ETFs watchlist? What I want to end up with is an All optionable ETF watch list. But I need an All ETF watch list to do this. And ThinkorSwim support said I would have to add them one by one and their are probably thousands of ETFs with new ones added all the time. I don't see why a brokerage doesn't have an All ETF watch list.
Can anyone help me with this?
Thanks,

There is a public scan category for all etfs, and another for all optionable. The two can be intersected.

Thanks, for try to help. But I wasted many hours trying that and not getting the correct results.
So I then starting looking through those lists and found that they were missing lots of ETFs. and hadn't been updated for many years. So then I emailed ThinkorSwims customer support and they said that they don't update the lists in the software?
So it is a waist of time trying to use those lists for scanning and trading, because they are never updated.
I ask the customer service, why have the lists available, if they are not updated regularly.
Any other ideas on how to make a complete updated list, would be helpful. And then another problem comes, how do you keep a list updated as new ETFs are added and removed?
Since a brokerage has all etfs that anyone can trade, I can't figure out why they don't have a scan button where one for starting a watchlist can just click and the software finds all etfs that the brokerage has and puts them in a watch list. Then you can do that once a quarter or so to update the list.
Anyway, thanks for trying to help. At least I know, the scanner is not worth using unless you have your own watchlist that you make yourself.
Thanks,

One other thing about this. On the Ameritrade website they have a page with ALL ETFs. But, there seems to be no way to get them into a watchlist, unless you do it one by one etc? Nott sure why, since they have a list of ALL ETFs, that they also don't have them available as a watchlist?

If you can find a more accurate list, you can edit the watch list, and import it manually.

The platform can only do so much, and we're limited to the tools at our disposal.

There are 2800 ETFs currently on TDA's master list.
It is possible to cut & paste them into an Excel worksheet and import into a watchlist, using this method:

Thanks, I don't know anything about Excel, but that seems like it may work. I will have to learn how to do that.
Now to find out how to that with excel .
It is still can't understand why a brokerage doesn't have an All ETF watchlist for their users, that is updated often?
Thanks for the info,
