Change the room description on the invoice

On the invoice, the word “room” appears as the item description. However, I sell apartments. Can I replace the term “room” with “apartments”?
I would like to replace the word “room” with “residential units” on the invoice. How can I set this up?
To change the room description, go to settings/room-categories. Click on a room category and, in the Room/Term section, select the correct designation for the room category.
