Pre Market High Low Horizontal Lines

[papio271]

I have got this indicator from the internet, However it plots the high and low of the combined post market and pre market sessions. Is it possible to have a drop down menu or a check box that when selected only gives the pre market high and low for which the session begins at 4 AM New York time?

Thank You
