I do the same thing - create PC presets, and a lot of FX Chain presets.
Many times, I'll toss the FX Chain Presets in the Bin when checking out a track - like a Limiter and/or Comp and/or EQ - most have Span in there as well.
If I end up wanting it out of the Bin, I just D&D the Preset from the Bin to the PC and it inserts an FX Chain.
Any tweaks to the FX are retained going from the Bin to the PC.
