Each room on your proposal has the option to add Labor Items.
You can find an item you've already created by scrolling through the list or typing the name in the search bar.
Once you've selected the item you want in your room, the Add Selected Items option will appear active.
Labor is then listed at the bottom of the room with a wrench icon. These items can be rearranged within areas as desired.
Adding New Labor Items
To add a new Labor Item, from the Add Labor window, click +Create New.
Next, fill in the fields for Labor Name, Unit Cost, and Unit Sell. Once all three fields are filled in, the Create Labor option will appear active.
Then select the new item from the list to add it to a room.
