Ability to mass edit images without metadata

I am requesting, if possible, a feature to mass edit images that dont have metadata due to editing in photoshop. It could be sorted by the model, with the ability to inject the bare minimum amount of metadata required to be acceptable, like the model name, or some basic prompt or something. The reason for this being, I am going to have to edit thousands of images, which I wont be able to do for a number of reasons.
