Im trying to make it so when i research, say booster upgrade 1, it'll add an item to merchant, which would be booster 1?

Simple,

    Events
        Unit - A unit Finishes an upgrade
    Conditions
        (Unit-type of (Triggering unit)) Equal to *unitthatupgrades*
    Actions
        Unit Group - Pick every unit in (Units of type *Buildingthatsellsitems*) and do (Neutral Building - Add *Booster1* to (Picked Unit) with 0 in stock and a max stock of 1)

Hope this helps
