Combine posted model sets

I don’t know if this feature exists, but if it does I can’t find it: I have a 1.5 model, and an XL version of that same model, but because I didn’t know at the time one could do it, I posted them as separate models rather than pusing the + button to add a variant. So each has its own model page. What I would like is a way to combine those two model pages into a single model page (same as clicking the + to add a new version) WITHOUT reposting, and without losing all the likes, downloads, and images posted to the gallery of either.

Basically, I have this: https://civitai.com/models/505539/delosian-bears

and this: https://civitai.com/models/646713/delos-xl-pony-trained

and want to do this: https://civitai.com/models/810016/by-chris-sutor

…without having to delete and repost.

Is this a thing? if not, can it be added as a feature?
