Troop denial

What if u could choose from a list of Cc troops, like if u dont want gobs or wallbreakers, then u choose everything but wallbreakers and gobs. iK u can use a troop request, but some mean ppl just do it to troll anyway. So when u request instead of a message,(which would be optional) it will list the troops that the person has selected. If someone gives u a troop that wasn't in ur selected list, than that person gets the giant bold annoying red letters saying, That isn't what your clan mate requested! Or something like that. I would really like if suprcell added this and I hope u will too!
