If I wanted to enable the feature for all registers in all tasting rooms I would enter “**”.
If I wanted to enable the feature for only register A in tasting room 2 I would enter “2A”. Where 2 is the tasting room number, and A is the register number.
Tip
Pro Tip! You can string multiple options together. For example if I wanted register A in room 1, and register B in room 2 it would look like this. 1A,2B
