It's definitely not possible under Save-As currently - you just get a (very long!) list of supported filetypes which are mostly just languages supported by the various other extension :-)...

Ah that's a shame - would it be possible to add a special luna command accessible from the command-palette that could do this?

Ah, no worries. Will wait for the vscode fix - thanks!

Seconded - came here after wondering why we get ExceptBy but not IntersectBy.

It seems to me likely that there will always be sets of "constants" which are either customer-specific or unavailable via MSGrpah or just "not imported yet". I'm hugely in favour...
