Place units in editor, spawn in trigger/script?

Is it possible to place units in the editor, save the information then needed to spawn them in those exact positions and have them spawn via a trigger or script?

This is an expansion to my previous post about deleting units from unused side missions, Im now wondering if its possible to spawn them only when side mission accepted?

Possible!

Here you will find the hand tools... ;)

Yes you can!

Use that script, it does exactly what you're looking for:
