SPI sniffing - possible enhancement

I am thinking about getting a BP v3 or v4....

I may have overlooked something, but the only mention of triggering (besides CS (chip select)) I've found was for "Logic Analyzer" mode.

Anyway, I read about SPI mode. The documentation claims it is implemented in the micro's hardware. The sniffing feature of this mode mentions capturing all, or only when CS is active. It does not mention any other triggering. I would like to use the AUX input as a trigger (selectable for start/stop and high/low).

I could code this myself, but if some one has already done something like this, I might not have to.

Has any one done anything like this? (for the SPI mode, not the Logic Analyzer mode)
