New Trigger-Effects (Feature-Request)

Hello,
I love making new maps and game modes with the scenario editor and wanted to use this thread to ask if it’s possible that we could get new trigger effects. Specifically, I would like to see a trigger effect that allows a selected unit to build a selected building/recruit a selected unit, or a selected building to recruit a selected unit.
Many thanks to the developers for the ongoing support of the game.

Kind regards
Straßenpirat.
