Training dummy units or hiding training Options

[The_Silent]

I want to hide one of the trained units one of my structures train so it can only be trained via triggers, and not by clicking the icon in the structures command-interface. (I want to hide units the training icon or find an alternative way to train them via triggers only.)

Edit: It is important that the training progress bar can be seen, as that is the whole reason for trying to use this method.

Any ideas?

Edit 2: Found a way myself:

First add the "unit" you want to be trained via triggers to "Trained units" of whatever unit you want to train it via triggers. The use the following triggers:

• Events
  • Map initialization
• Actions
  • Player - Limit training of "unit" to 0 for "player"

And whenever you want to train the unit:

• Actions
  • Player - Limit training of "unit" to 8 for "player"
  • Unit - Order "Training unit" to tain/upgrade to a "unit"
  • Player - Limit training of "unit" to 0 for "player"
