i don't know if it was discsussed before, but what about unlinking addresses? is there any option?
If i undrstood well removing some or all BTC from the linked address will unlink it.
I'm notsure.
Try it to chek if it works.
Removing the BTC will not unlink it. The address will still be linked but since there will be 0 BTC on it, it will not receive any Byteball.
