Changing BSSID separately

Hello everyone,
Here i am facing the issue of changing bssids in lede os. Requirement is to change in ssid parameters without refreshing other ssids.but when ever i change any ssid , it impacts on all the ssids and all connected stations get disconnected.As a developer i found there are 2 hostapd processes are running for each radio,which reloads every time on changes.But i also found for all ssids separate interfaces are establishing.
Please help me out with this issue.
