dpsk per wlan expiration

[tobias_brisach]

Is there a way to configure DPSK expiration per (not guest) WLAN, not global?

e.g.
In WLAN1 all employees will keep their PSK unlimited
in WLAN2 temporary workes after staying for half a year, so it expires after 6 months.

Both user groups are athentificated by an ads.

Thanks in advance

This would be something I would also like to do if its possible.
