How do I load my levels during development?

I wrote a level editor that allows me to load and save .json levels using a FileChooser object.

Stupidly, I assumed I would be able to load these files (sans FileChooser) in the game, but I forgot that Construct 3 is browser-based and this is not allowed.

My game will have ~200 levels and during development I will be tweaking/changing them frequently. Should I just keep all the levels in the Files folder in Construct 3, and then re-import them every time I change something?

What is the best practice for this?
