[Unsolved] Siege Tower!!!

I know how to make it so that a unit can carry other units but Im looking for a way to make it so that a tower can drop men off on the wall. Help would be great.

On which wall?

And just use the load/unload ability.

I think he's relating to like you enter one tower and you exit on any other one?

I think he thinks of using the tower of as a kind of "stepps" to reach the wall.
Like in Stronghold Crusader.

I think it is possible with triggers but it would be very difficult and so I would look for a different way...

Just change the 'Transport'(?) spell with different ranges and such, not that hard.

Yeah I just want it to be able to unload on a wall but I think that Divine Boss has a good idea but if it doesn't workd ill come back with more questions.

EDIT:
Divine Boss your method worked and thanks very much and thank you all for your imput.

I don't understand what he is talking about...

I often play(ed) Roleplay maps, they got units there at allows you to use Load on units from let's say, 1000 range.
