I see. currently there would be no way to do this out of the box. However I can see how this could be very useful. If one would dedicate a single vault to interface with one external tool of choice, the ability to mark a vault so that it specifically recognizes files and syntax that the tool uses would save a lot of effort. Do you mind submitting a feature request? We have briefly discussed similar ideas internally and it would be great to track an actual use case for this 🙂
