Ahh, Yep, same thing port and/or protocol for an address range. I haven't seen that accomplished via BGP. I know ATT will do it - they want about 2K more per month for that ability. All your traffic is redirected (extra hops ) through a firewall. So, it's a basic expensive firewall service. We have done both port based and protocol. But it gets installed by hand only on the connected port the customer.
From what I've seen, most of the major carriers don't filter trafficoutside of truly exceptional circumstances, or it's treated as a revenue source. If it's offered at all, it's often priced unattractively, because carriers often don't want to be in the firewall/port-filtering business.
