Map content categories to specific profiles/usernames

I would like to be able to map a feedly category to a specific profile/username e.g. My photography category maps to my photography profile/username and all items I like are shared/posted under that profile. Likewise my software category items are posted under my software profile/username,

Currently this is possible using 2 different logins, but I know I would like to be able to post content using different profiles/logins without having to logout and login again as another profile.
