Creating diagonal guides in indesign

This has been a requested feature on indesign uservoice for several years now: Turn paths into guides with the right click menu "Make guides" like in Illustrator.  

If you scroll down the comments Bob Rubey shares a link for a script that will convert objects to guides. The link is broken, but a simple search will come up with this link: http://kasyan.ho.ua/indesign/all/convert_object_to_guides.html 

Objects still will not snap to the objects like they do with guides.

Sometimes I set up a non-printing layer when I need a diagonal guide... because the Line Tool can draw diagonal lines just fine when you hold down Shift. All I really need out of my guides is that a) they should not print, and b) stuff should snap to them (if I have Smart GUide Options -> Align to Object Edges checked; this is checked by default). So this works for me for those one or two projects every year where diagonal guides would be helpful.

If you need something beyond that, then my solution would probably won't work for you.

Not directly, and as far as I know, no plugin either.
