Banish with re-issuing previous order

[ThaAthael]

Hi folks!
I'm in need of a few triggers concerning the banish ability.
I need units under the banish ability to gain their rightclick on pre-placed model order back once the banish buff disappears (means: the effect ends).
In addition, when entering a certain region (or coming within 200range of the ordered target, I don't care which of those 2 possibilities), I need those units to stay there - either being paused or running circles around the right-click order unit, it's up to you.
What really is important is that those units won't attack any other surrounding units (though these are attacking the banished ones), just their original target.

I've tried this several times now, but my attempts all lead to nowhere

If anyone of you would be so kind to help, this would allow me to finally have 50% of my TD project done (see link in signature, map is unprotected.. if you take a peek, the banished units shall attack the targeted ziggurat when back to normal again, the beforementioned region are the 'attackplayerxyz'regions).

Of course +rep and credits

Well create a periodic event that checks if the unit has the buff, if it does and it's in your specified regions (Unit - Unit is in Region (Boolean comparison)), then if the unit doesn't have the buff anymore, order it to stop and remove it from the unit group you added it into to periodically check.
