Edit MAINCFG in Zone Builder?

Hey guys, I was curious with the Zone Builder, and I was tired of editing the MAINCFG through SLADE3, Saving, reopening the map in Zone Builder, and I wonder: Is there a possibility that I can edit the MAINCFG through Zone Builder ?, if not, I think it is recommendable to put that function to edit the MAINCFG script in Zone Builder.

IIRC somewhere in one of the menus in the toolbar, there's a "scripts" option which allows you to edit the MAINCFG and any other kinds of SOCs and even Lua scripts.

You can also open the script editor menu by pressing F10.
