Choose which Whop business each app sells under (several brands in one workspace)

A creator runs more than one brand, each with its own Whop business, from a single Overskill workspace. Today every app in the workspace sells through the one payments company Overskill provisioned for that workspace, and there is no place to pick a different business per app when turning on payments. Requested: a per-app choice of which Whop business the app's products, checkout, and payouts belong to, including businesses the creator already owns in Whop.
