However, in the eeschema dialog for menu item File|Page Settings… There are only 4 comment lines and no obvious way to add or modify these variables in the dialog. I was digging thru the code and got as far finding the menu item triggers ID_SHEET_SET, which links to EDA_DRAW_FRAME::Process_PageSettings in the dispatch table of sch_edit_frame.cpp. At that point I decided to see if anyone on the forum knows anything about this.
I’m guessing that this is all just hard coded in ::Process_PageSettings but maybe someone else knows already without me burning a half day digging. (@bobc ?)
Thanks in advance for not replying with guesses, unrelated questions, or hijacking my question with some other discussion.
