Hey there, @Ava_Crafts -
Welcome back to the Community.
At this time, you're only able to add either the discount or the coupon. I just tested it my own Online Store and Point of Sale Dashboard. If this is a feature you'd like to share your voice about, I can suggest adding this to our Feature Request Board.
On that board, it shows our Product Team the specific features our sellers are looking for with their businesses.
