Editor: in View Editor, Replace all frames with Sprites from Folder

Describe the problem

Hi all. I love the feature to "Add all sprites from folder" when adding an animation to a loop, but it has one small issue that makes it a tiny bit annoying to use.

It always leaves a blank sprite at the start of the loop which I then have to delete.

Suggested change

Could there be a "REPLACE all sprites from folder" option that replaces all the frames in a loop, as opposed to just tacking them onto the end?
