Feature Request When adding a series, no option to add "related series"

I just noticed that there's no option to add a "related series," when adding a series to the database. Not sure if that was an oversight, or if you just prefer users to add it later if/when the series gets approved.

 

I think the related series feature came after the 'add series' feature so I never thought about it. I prefer if users just wait till it gets approved then add the related series later though.
