When adding a bottle to your inventory, on the Add screen, there is a drop-down menu for:
- Cellar (e.g. Home, Office, Long Term, etc.)
- Location (e.g. Fridge3, Back Wall, etc.)
- Bin (e.g. Row3, B6, Top Shelf, etc.).
If you tap on them, it will give you the ability to add inventory to an already existing Cellar/Location/Bin (or add a new one by clicking the +Cellar, +Location or +Bin beneath it) and assign a value to the newly added bottle.
