Using one SSID with multiple VLANS

Here is the scenario.

We have a client that currently has a setup with 15 SSID's. And each SSID is associated with a VLAN. It's a shared office space, with rented offices, and traffic is kept separate. However this is causing issues because there's way too much noise. Too many SSID's close to each other. 

What I'd like to know, if even possible.

• Can we assign 1 SSID for the for the entire area.
• And then based on the password used. Traffic is routed on the appropriate VLAN.

This can be done with Meraki.

Or maybe there's an alternate scenario that can be used in this situation.
