Uploading skins from computer to editor?

So I’ve gathered that there is no way to upload a skin from your computer to the online editor here. None of the threads I’m seeing seem to actually address the issue. If there is some way to do this that I’m too blind to see, I’d like it if someone could point it out for me. If not, then could someone please consider adding that as a feature? I have a skin I made in the editor that I saved to my computer, but now I want to change it further and I can’t because it isn’t in the gallery(I forgot to save it there) and I don’t want to start all over again. Thanks in advance for any aid rendered. Curses in advance for any inconvenience unaddressed :stuck_out_tongue:
