So for range specification, this is typically constrained via the Windows_SDK.json (ranges are already supported, which more or less gives you a similar functionality). In specification of your precise compiler version, you have the “latest” option that you can provide for CompilerVersion attribute specifically. [mention removed] - any feedback on this?
It is not currently supported but could be added. We can make a Jira for tracking and I can look into it but I won’t be able to commit to getting this in for 5.6.
