Flex6300 + RX with 2 instances of wsjt-x v2 on 60m

due to the situation that hams have to use two different frequencies for wspr activity on 60m, I tried to configure my equipment for decoding both signals at the same time. In Austria only RX is permitted on 60m :(
Flexradio 6300:
Slice 1: RX - Audio DAX RX1 - SmartSDR COM 4
Slice 2: RX - Audio DAX RX2 - SmartSDR COM 5
more tricky was to start wsjt-x in two instances.
Thanks ve2ebk for the post in groups.io FT8 Blog.
first instance in the windows cmd window with wsjtx
second instance with wsjtx -r=2
all configuration entries are empty in the new instance and you can configure it as you need it.
Wsprnet database gets the correct frequencies for all of the logged calls.
