Connecting fixed belt loop to fixed horizontal bag strap.

Sorry if the title is a bit confusing. I’m trying to have a quickish connect coupling of a small camera pouch with a small shoulder bag. I like both of them individually and want to keep the function but pair them together securely sometimes.

Neither can be unbuttoned etc.

I hope that’s clear and thanks for any thoughts!
