You can duplicate that adjustment using the editor, and make the following two changes:

1. Get rid of the text in the "Custom Expression" entry in the details, to remove the item selection menu.

2. Replace the script with this (for potions).

   ~ If we're not enabled, get out now
   doneif (field[pIsOn].value = 0)

   ~ iterate over picks in hero container and tag all potions as free
   foreach pick in hero from MyGear where "gType.OilPotion"
      perform eachpick.assign[Helper.Free]
   nexteach

For scrolls, the relevant tag would be "gType.Scroll" instead.
