Remote User Access different networks?

I’ve got a single user set up using Network / Remote User Access via PPTP, connected to one of my VLANs. Works great.

But now I have a different user, and I want that user to be given access to different things. Is this possible?

Basically I want user1 to be on VLAN1, and user 2 to be on VLAN2 when they connect via PPTP.

Is such a setup possible?

An acceptable workaround would be if User1 has “everything” access (WAN/LAN, etc, no isolation), and user 2 is fully isolated and can only access the WAN.
