Sorry Jimmy, you will need to export. Bounce Selection will not do as you need… 
So, MAKE A COPY of the track you wish to process and mute the original.
On the copy, reset the level to 0db if its not there already. Now, you can route this channel straight to the output master. Solo the channel, set the locators and export. Tick the box to re-import to the pool. Deal with from there as you desire… I would re-import to a new (again copied) track immediately below the one I’ve just processed to keep things tidy (plus it will have all my insert/send/eq settings intact from the original). If it still isn’t quite right, I can delete what I’ve just done, and quickly go back to the ‘process’ track and retry.
Re-assign the routing back to your original group, reset the level to the original, mute the copy track etc…
SB’s VariAudio is cool mind, in that it is so integrated - you can lose a few steps above. I’ve used Melodyne Assistant version and it is pretty sweet though - and you can adjust AMPLITUDE of notes inside it too…
But, it is all a bit convoluted and would be my only gripe with the product - i.e. it won’t render and replace in context, for speed/convenience.
Of course, I’ve now learned to deal with any of this sort of er, ‘help’ that’s required, as soon after tracking/overdubbing is done as possible…! I just quickly go through and check against a single guitar or synth tone perhaps. Phrasing and timing is more tricky to adjust at this point (without the rest of the band/music), but you can at least ensure any pitching malfunctions are sorted… which IMHO stand out more and are harder on the ear to deal with - as opposed to any minor phrasing (performance) tweaks needed…
Anyhow, good luck…!
