Is there any way to link stories that are already on the AO3 without having to go upload them again at the actual Beholder page? My 2010 Beholder story is already on my AO3 page, so I tried to link it to Beholder by going to "Edit Work" and adding the Beholder community under "Post to Collections/Challenges." AO3 responds that it can't find any community or collection under the name "hp beholder" or "hpbeholder" or "hp_beholder." It will let me add tags in those names, but just adding a tag doesn't actually upload the story to the community. I've tried typing in every variant I can think of, using "community" and "collections" and neither, but none of them works.
I can do the whole "Post New" thing if necessary, but if I don't have to, I'd just as soon not (although I've spent so much time on it by now that I could have done a complete upload twice over.)
