Can I change the customtypes location from slicemachine.config.json similar to how the libraries property let's me move the slices folder?
I wouldn't recommend it. While it is technically possible to move files around in your project to see how everything works, this approach may lead to conflicts and unexpected issues when running Slice Machine. Some kits may rely on specific file locations, and moving files could disrupt their functionality.
You can try it out as long as you don't commit changes to your main branch and see how it goes.
It is difficult to predict the exact conflicts that may arise from such changes. Instead, I suggest following the recommended practices and guidelines provided by Slice Machine to ensure smooth integration and avoid potential complications.
