[Solved] Adding sell-able units into another unit (via triggers)?

[Yours Truly]

Title.

I can't find a trigger that adds a unit that can be bought into another unit (in this case, a building)

• Neutral Building - Add Footmen to (Triggering unit) with 0 in stock and a max stock of 1

Only works when the unit has the "sell unit" skill

Thank you for the fast response
