If this doesn't already exist, can we make this a ticket for an enhancement?  I can probably make you a PR for it if you tell me what you might want to call the view.

Maybe all I need is to make a link to a card as if it were an external URL.  If I could link to my PDF in a way that opens the file instead of going to the the wagn card first, that would satisfy.  Maybe change the card link to an inclusion?  Maybe I'll try that.

Yeah, that works. Just use an inclusion vs. a Link. Default view seems to work, but sometimes you may want 'core'.
