How Can I use the same app for more than one Business

How Can I have a way to Show a different home screen , services per business as User enter the app?
Is there a way to control that using the same app but different access ,look per business

Same Booking app but if a specific business is selected or passed through a QR code I get to a specific home screen.

Are there developer that can make changes to App they created ?

You can try this approach for URL params.
