expand network access point with hotspot

RouterOS Wireless Networking
1

I have a running RB2011UiAS. With multiple SSID wlan. One uses the hotspot function. Going fine.

To extend coverage going need to add two access points, going for 2x wAP. But, How do I get the other two AP’s give also multiple SSID and use the (already) hotspot?

Any direction is appreciated…
