Is there something like Vision Client Tags in Perspective?

As is known to all, the Vision Client Tags allow users from different vision clients to operate without being affacted by the others,
while if we wanna achieve the same goal in Perspective which is to let the users operate their own stuff individually,
how can I make it?
Is there any function which can work as a substitute of the Vision Client Tags?

Custom session properties will allow you to store values unique to each session but persistent across views, browser tabs, and other parts of a session.

Thank you so much my friend!
