I have 181 update-groups.
The reason why I am having this is that I want to allow my transit
customers to send us BGP communities that will allow them to control
the announcements to individual peers, rather than to regional peering
groups. I only can see 1 route-map per peer as a solution here. Or is
there a better way (regexp?) to handle this?

The BGP communities we are getting from the customer would be
6500x:ASN (x = number of prepends: 0-4, ASN = peer ASN).
