Your understanding is incorrect. Please watch this:

If you have time (40mins to an hour), I'd also suggest you watch this):
The meat of this one starts at 16:48 https://youtu.be/BYTlN6wjcvQ?t=16m48s
but the preamble is worth watching for other reasons too.

Out of say 15 tracks, there would be 4 that need higher quality

your audio interface runs at one sample rate. all tracks not at the same SR
would have to be resampled. Not a good idea.
