two 2m-Transverters for diversity reception on 2m

[DF1AL]

How can I tell the K3 which of two 2m-transverters (XV1: K144XV-internal and XV2: external transverter connected through KXV3A RX-ant IN) to address? When I enable both transverters in CONFIG (XV1 ON = YES and XV2 ON = YES) the K3 will always adress XV2 and does not leave me a chance to choose which transverter to use with either RX input. This would be useful for diversity reception with XV1 connected to the MAIN rx and XV2 conntected to the SUB rx.
Has anybody succeeded to use two separate 2m Transverters with both RX paths for diversity reception - and how?
Any suggestions welcome!

Joe - It might be useful to upgrade to the latest K3 v4.10 beta
software. It provides some changes to the way the transverters are
addressed.....

* K144XV BAND-DATA OUTPUT ADDRESS RANGE INCREASED:
Originally, CONFIG:XVn ADR was always set to "INT TRN1" to enable
the K144XV. This set all band data outputs on the ACC jack to 0. Now,
XVn ADR has of "INT TRN0" to "INT TRN9" for the K144XV. Band-data
outputs are set accordingly. This may be useful when the K144XV is
used as an IF for higher-band external transverters. (If you have a
K144XV, the original INT TRN1 will now be INT TRN0 in the menu.
This is the new recommended setting if you're not using external
transverters in conjunction with the K144XV.)

I'm not sure if you will get true diversity reception unless the
transverters are identical and have frequency locked oscillators.

I stand corrected if there are experts on this forum !
