Have separate snap.as galleries, for each blog

Hello I have made this question but in “general” discussion here

In short words, I have a pro plan with multiple blogs. So let’s assume I have the following blogs:


The problem is that snap.as does not distinguish accounts. So if I give the link of
snap.as/y to someone, he can also view the galleries of the other two blogs.
In the discussion link provided above @matt was answering to another user that soon they would support multiple Snap.as identities under one account

Has this feature been implemented? Or is there a workaround?

For what I am working on it is mandatory that the galleries of one blog are not visible by the other.
