DHD Glyphs Buttons

[WitmenCz]

Hello there,

i am trying to set up goblin merchant as DHD Panel from stargate series.
Building have ability to choose unit as usual, what makes sence - u can manipulate panel only with closely present unit.
I was not able to figure out how to use skills on that neutral building only with unit presence so i decided to make whole thing with sold items, BUT.....
I cant figure it out how put sold items into (added) inventory of shop instead of hero, also in matter of bypassing full inventory check of customer.

Thanks for suggestions
