Lyrics - "vocal" vs "sheet" vs "priority"

With many many songs in the set, I have a mix of lyrics solutions (no one standard right now)…some songs have “vocal” lyrics, and some have “sheet” lyrics.

So instead of having to toggle/choose “vocal” vs. “sheet” song by song, it would be helpful to have something like “priority”.

For instance, in addition to the way it is now (forces the user to choose), maybe 2 more options could be available:
(1) " ! sheet" – which could mean, show the sheet if there is one, but if no sheet is found, but rather there is “vocal” content, then steam/show the “vocal” content.
(2) " ! vocal" – the opposite of (1)

Well, maybe this is an oddball idea. (Never hurts to ask)

Isn’t that already possible with OSC?

I appreciate the reply. Good question. And yet, I am just a mere mortal, trying to corral technical stuff (ie, I left programming decades ago, but ok w/ MIDI and BOME Midi translator)…trying to more and more emphasize a focus on being a musician. And yet, I am open to an example. If someone shares an example, and it seems like low-hanging fruit, I may jump in. (thanks)
