The new ARN FOBs use it for COS but yes you can drive any bit you want.
This is nothing new. It has been there for a long time.  For the FOB you
just set the bit you want to output on assuming it is available adding this
in simpleusb.conf -

gpiox=outy    ; where x = bit number 1-8 and y is 0|1 for initial output

Then in rpt.conf as an event you add -

For RX indicator -

cop,62,GPIOx:1 = c|t|RPT_RXKEYED
cop,62,GPIOx:0 = c|f|RPT_RXKEYED


For TX indicator -

cop,62,GPIOx:1 = c|t|RPT_RXKEYED
cop,62,GPIOx:0 = c|f|RPT_RXKEYED

Where x is the corresponding port from the gpio setting in simpleusb.conf
