configure a Virtual AP with the main interface set as a brid

Hi, I’ve read that to configure and virtual AP the main interface has to be configured as an access point.. Is there any way to make an virtual AP if the main interface is configured as a station??
Becuase I’m trying to use the MK as an access point connected wirelessly to another AP..
thank you very much

It is not possible. You need second wireless card for such scenario.
