How to build my custom ModelBehaviorDefs and html_ui files straight into packages?

Hey, I’d like to know is there is a simpler way of getting my custom
ModelBehaviorDefs and html_ui files straight into my packages when building?
I’ve been copying them into the Packages folder and then using the
MSFSLayoutGenerator.exe tool to load them into the final package. But it’s
kind of bothersome to have to do that everytime I build my packages, is there
another more straightforward way to get those files into my final package?

Add them in the package definition with the “Copy” type.
