I just wondered why it isn't possible to flag images for being over the "five re-used base" limit.

Forgive me if this has been answered before, I searched the forum but couldn't find anything.

I was just checking tags for my tagbot and found an avian post with five children, with the only difference being the colour of them, I went to flag then then realised it wasn't an option.

(Not linked as I'm not sure how strict the "back-seat moderating" rule is. I'm pretty sure it doesn't apply to things like this, but I'd rather be safe than sorry.)

I thought something along the lines of the option and five boxes for the other post IDs could work.
