Is there an xml tag that allows a unit to be sent to the capital and exchanged for gold, sort of like a treasure unit. If not, is there a modcomp that allows it?

you can take a look at the Vikings Scenario from Warlords, in which you had a "Treasure Cart" unit, which had to travel safely to your capital to cash in for gold.

You can use teh Treasure Unit from teh Viking Scenario, and have its "ability" be the same ability as the Great Merchant. the "conduct trade mission"

I believe all that does is generate a sum of gold depending on distance from capital, but can only be used in a foreign city. That Not quite what your looking for, but its available.

I was looking for something that can built outside of the capital and returned to the capital for gold.
