Help!

I have a rather simple yet annoying question:

I want a building which can be built by a computer player, after which allied players can summon heroes from that building. I want the summoning of heroes from that building to either take time, or instant but with a stock start delay.

Thanks, Remy.

Maby you can edit a player build shop to train units if that is possible, or items that fire a trigger to create a hero at the location of the shop.

Why dont you just have the building sell heroes? Have the stock start delay like you suggested. Then anyone could walk up and summon a hero (after waiting for it to be created).
