Changing targets with preset spells

Theres a few spells, town portal, dark summoning, staff or teleportation. That you can only use on your own units, regardless of how you change the targets allowed field. Is there any way to change this to allow you to use these abilities on enemy units?

no promises but i'm pretty sure you can't do this. if you want a spell where you can basically mass teleport to anyone than do it with triggers
tell me if u need help with that
