How to add/remove HUMAN BUILD ability by triggers?

[Flux]

Is it possible to remove/add the build ability by triggers? I'm basically doing something that gives you a build-human ability when you acquire a specific item. Unfortunately, the human build ability is not an ability but something in the unit itself (Structures Built). Is it possible? If yes, how? I no, how can I use 2 build tiny (something)? Because when I give a unit 2 different abilities with different base ability but both based with something that starts with "build tiny (farm, altar, etc)", it won't work.

Only "worker" units have the Build ability.
I'm not sure this will work, but try:

• Unit - Add classification of A peon-type unit to (Triggering unit)

Remember the unit must be of the race Human to get the Human Build.

That didn't do the trick. I tested it and remove a peon-type unit to a worker after 8 seconds of elapsed game time but there is still the build ability there.

Try to let your unit NOT have the "worker" classification from the beginning, and then add the "A peon-type" ingame.
