pim auto-rp priority missing?

hi list,

I was wondering how to create a backup RP for a certain group when using
Auto-RP. I cannot configure any priorities as you can when configuring it
for use with a bsr?
I checked the doccd but i am not able to find a similar function? How does
the mapping-agent decide which RP to use when two RP's announce them same
groups in Auto-RP mode?

Thanks,
