Hey there.
I'm not sure how one would set this up, to be honest. I'm not at all familiar with how touch inputs are handled in the first place, and since touching the item itself would simply select it, I can't think of any other touch action that wouldn't also be touching the item. Even something like touching the icon on the item's name wouldn't work because it'd still be part of the items selection rectangle. Perhaps some sort of onscreen button might work, but again, I'm not really experienced enough with how touch controls work.
I'd say the best bet would be to find a plugin that allows you to map keyboard controls to buttons on screen, and use it that way for now.
