C3 edit XML with external editor?

Is there a way to edit XML file imported to construct 3 with an external editor? In C2, I use Visual Studio Code which can do Emmet. It also helps close tags. This makes editing so easy. C3, however, has me edit XML in the browser and it isn't as convenient.

Right now, I copy the code from the browser -> Code. Edit it. CTRL+A and CTRL+V back into the browser. Is there a more direct way to do it?

If you saved your project not as a .c3p but as a project folder, you can edit the .xml directly using your 3rd party external editor. The XML file should be located inside the project folder directory.
