Allowing Multiple Trade-able Units?

[Sutsuj]

Hello,

I know that you can change which unit can be traded from the worker to whatever you like, but I don't know of a way to allow multiple units to be traded. Is there a way to accomplish this?

The closest I have is the following:

Have an upgrade chain, where the base unit in the chain is the trade-able unit.
Have the base unit be the unit created by the "build army" capability (and re-brand "build army").
Give every unit in the upgrade chain the "build army" ability, so they can be converted back into the base unit and be traded.

Any suggestions or editor hacks? I'm using the Quintillus Editor.

Well, I hope I'm not too late! You should have posted this in the main, "Creation & Customization" forum, not this sub-one.
