We've noticed a bit of a bug in the Square for Restaurants POS — our business has a special tax (fee) setup when the dining option is set to "house" or "charge" — we've added a special tax to be applied on the condition of a dining option change.

If you open a check with one option and the customer decides to change the dining option, the change in dining option doesn't re-apply the conditional tax rule to the entire bill — it ONLY works if the dining option is set from the start.

Furthermore, it's really annoying that if you have a bill with multiple items, and you select say (4) items to edit — you can only comp, void, move, remove the items from the screen, you cannot bulk edit taxes on multiple items. You have to individually edit EACH item to re-apply the tax that should have been globally applied with the dining options change. 

This is highly inconvenient and not real-world — if you have a tax option condition that relies on a dining option, and the customer changes their mind — the rule should be conditionally re-applied on change.
