Beginner question: Autocomplete with multiple tables?

Hello,
I’m completely new to wappler and I have a difficulty combining different fields in an autocomplete text input.

So, for example I have 2 tables of ‘cars’ and ‘bikes’ (both have fields of ‘id’ and ‘brand’). How do I have both in the autocomplete so the user can get suggestions for cars and bikes by typing the brand?
