Can I update the programmers list in the Arduino IDE?

Is it possible to tie-in the Bossa program to the Arduino IDE??
This is my first guess as to what to add to the …/hardware/arduino/avr/programmers.txt file:

bossa.name=bossa
bossa.communication=usb
bossa.protocol=stk500v2
bossa.program.protocol=stk500v2
bossa.program.tool=bossa
bossa.program.extra_params=
