Use a different mail address for shared photo streams

Hi everyone,

is it somehow possible to use a different mail address as the sender when sharing a photo stream with others? An example:

• My current Apple ID is myname@mydomain.com.

• This Apple ID has several other email addresses associated with it, one of them is the free @icloud.com address.

• I would like to use this @icloud.com address when sharing photos via iCloud.

It is possible to set your 'sender ID' in FaceTime and Messages. I would like a way to set it in Photos as well…

Thanks

Björn
