You could set the whole reveal to be similar to what the wall has set up as the side surface, but I don't think that is what you want either.
You could probably change the script for the reveal setting, but that requires a lot of digging around in CALL-ed objects to find where they are setting up the parameters. It might save time for the 366 windows, though maybe not.
You could also use a shell in the U-shape of the trime with the proper thickness. You can copy that around in elevation and adjust as needed or put it in hotlinked modules for the different shapes.
