How do i remove multiple episodes from my watch history in bulk?

My ex-gf watched 6 seasons of Lost on my account, i wanna delete them from my history, but it appears the only functionality i can find is by deleting each episode one-by-one. This involves 2 clicks per delete, and having to wait 1-2 seconds per delete for it to register. I aint doin that. Surely there's an option to select multiple somewhere that i can't see?
