Yes, you can create a section called:
on_debug { : goto "location"; : set_true "has_searched_drawer"; : create "lamp" target="inventory"; }
This will have priority over on_startup, and you can setup your test there. Make sure you comment out this block before you compile the full game.
To comment out a block select a block in the editor, then press CONTROL + / , to uncomment out a block, select the commented out region, and press CONTROL + / again.
