Any Meal Planners/Recipe Managers with support for pre prepared meals?

Mealie's meal planner looks exceptionally useful, but unfortunately we don't always have the time nor the energy to cook a full meal each night. Therefore around half the time we usually rely on pre prepared meals from the store. Unfortunately, it doesn't seem like any of the main selfhosted apps I've tried (Tandoor, Mealie, KitchenOwl) really support them at all. Understandable since they're primarily recipe managers I guess.

I noticed Mealie would let you enter custom text under a meal planner day, which is helpful at least, but it would be nice to make use of the auto planning and random selection features too.
Is the only real way around this to make a bunch of empty recipes for each of the meals we usually buy? Are there any other selfhosted Meal Planning apps that would support this?
