Why can't I PASTE an image into Photo AI?

When working with other photo editors, Corel and others, I can simply copy an image from the source and PASTE it into the editor. Why is this elementary feature missing from Photo AI?

At this time, Photo AI does not have the direct paste functionality you’re describing, which is a feature found in some other photo editors.

We understand that having a copy-paste feature could be a useful convenience for some users, and I’ll make sure to pass along your feedback to the development team.
