I don’t know anything about the PBC10, but would the addition of a Morningstar ML10X help you out?  You’d be able to reorder all pedals connected to it (pre or post) per preset.  So one preset has your H90 Pre for the Vibe or Pitch effects, another preset might have your H90 post for delays and reverbs.

If you try using the H90 as Pre & Post at the same time, you lose the gorgeous stereo delays and reverbs.
