Multi-Hero abilities Removal/Learning

[tiaramisu]

Hello! i'm having trouble by making a Multi-Ability for a hero , What i mean by multi-ability?

lets say Hero A Has 1 ability , ''Ability A''

I Made a triiger so when you choosed ability A you had 2 choices.
''Shockwave'' or ''furious stomp'' (Via dialog Box) Now my problem comes here.
I managed to make a trigger (with leaks prob) but that levels the choosed abiltiy sucessfully.

And Since ability A is a ''Dummy'' ability it learns it with the triggered one as well..

For example

Hero A learns ability A (dummy) , I Choose shockwave and i sucessfully learn shockwave but i also learn the dummy Skill , occuping One slot. so how could i make the ''Dummy'' ability to dissapear?
and yes i know about spellbooks but i can't figure out a way to make it work (i don't use jass btw )

that's all , thanks! ^_^

I think a good choice for a dummy ability would be attribute bonus, as it gives you the option to hide it.

mmmm i'm using a random human ability as ''dummy'' but for testing purposes only anyway here's the map so you can see by yourself what i'm tryng to manage c:
when you learn the skill you can choose wich one you want to learn and after that you can level it up by upgrading the ''multiskill'' ability but the problem is the icon occuping spaces in the hero's skill bar
i attached a copy of the map below

Just replace the multiskill ability with a ability based on attribute bonus and set "hide button" = true
If you test my map, you will see, that the paladin can level up the skills, but no buttons are displayed.
