OTOH, if you're having them RTBH an IP, do you really care about any of 
the other community tags to do various TE "stuff"?  For each neighbor that 
supports RTBH, the output route-map for that neighbor should have as its 
first permit entry, a check for your internal blackhole community with a 
set community for whatever that neighbor needs for RTBH.
