Select a specific beta after profile installed?

I installed the developer profile on my iPhone and Apple Watch to download 14.5RC and WatchOS 7.4RC but my only "Check for Update" options are 14.6 and 7.5.

I finally downloaded and manually pushed the .IPSW file to my iPhone, but how do I install 7.4RC and NOT 7.5 B1 to my watch?
