Can I change studio info on amv entry?

[seabird]

I'm not sure what to do. I changed the name of my studio (where i am the only member *cough*), so i'd like to change the studio information on the two amvs I made...Can i even do this? Its not an option on the normal edit, nor an option for locked info changing. I suppose that means its not possible to change >_>
And if im just really stupid and missing something obvious, i apologize...
Please help, o knowledgable admins/senior members/nice people?
