Rename shared calendar

Hi,
I was wondering if there is/can be an option to rename a shared calender for which I got all of the editing permissions?
I am asking as my (mailbox user and family account member) partner's name is not a short one like Doe, John but rather like Donaldson, Jonathan. Since the name of the shared calender appears to the end if the name, all his shared calenders usually look kind of cryptic (Donaldson, Jonathan: ...) until I click/pull/read to the very end of that long line (Donaldson, Jonathan: Swimming --> Oh yes, that one I wanted)

Thank you.
Best regards,
Carina
