Help building a gap up scanner in ToS

Hi everyone,

I would like to build a scan that looks for certain criteria but i am not sure if it's possible to do this with the built in TOS scanner tools or if a custom scanner is needed.
Basically, the main criteria i am looking for is to find stocks that have gapped up a certain % intraday within the last 20 days. For example, find all stocks that gapped up at least 30% intraday in the last 20 days. It should also scan with pre-market prices included, not only regular hours.

Is it possible to build a scan like this?

Any help is much appreciated.
