In the "Assign the light frames" I use to choose RGB with my ASI294MCPro (colored).

I wish to use a new filter : the Optolong eXtreme duo band with OIII and H-alpha only (both together)

But In the "Assign the light frame" question I can only choose between OIII and H-alpha... and not both of them...

What should I choose ?
