Make it a 2-gang box and then you can separate the switches.

Or if you want to keep it a single gang opening, automate the master side of the 3-way as well as the garage light. Then you could make the switch location in the picture a 2-Button keypad (one button for each load).

That’s how I would do it in Crestron, I’m not sure what keypad options Lutron has.
