How to retroactively add service catalog buttons to already created services? [SOLVED]

If I add a custom button to a service catalog I would expect that new custom button to be added to all services that were created with that service dialog. That is not the case. Is there a way to add the newly created button to all existing services that were created with that service catalog?

Turns out if you just add the button to the service catalog it gets added to all already existing services. Sometimes the simple solution is the answer.
