Just to add another possibility: if you don't have full control over the hostapd 
configuration, you might also find the "start_disabled" parameter useful.

When enabled (i.e. when start_disabled is set to 1), the interface won't be 
beaconing when hostapd starts. Next, the "UPDATE_BEACON" command can be used for 
the interface to start beaconing.

With this in mind, you could pre-create one or multiple BSSes with 
"start_disabled" set to 1. Once an interface has been configured and you want to 
start using it, you can send the "UPDATE_BEACON" command to that interface 
selectively.


Kind regards,
