Animation bulk upload request

I want to make a few objects with similar animations, but don’t want to remake or upload frame by frame every time. Could you make something that allows us to use the sprite sheets we can download to upload the sheet as an animation?

Say for example this animation, that I could upload it and it already sets all the frames in the animation.
This would be extremely useful to me and maybe some other people, especially since I’m working on a different version of Wizardry’s text printer, and don’t want to upload every letter and number frame by frame on all my games, plus other users could just use my sheet to upload as an animation.
