  Not directly like this. But if you have few known communites, you can do
next hardcode:

function add_community(pair set comm)
{
	if ( (123,555) ~ comm ) then
	   bgp_community.add((123,555));
	if ( (123,666) ~ comm ) then
	   bgp_community.add((123,666));
	if ( (123,777) ~ comm ) then
	   bgp_community.add((123,777));
	if ( (123,888) ~ comm ) then
	   bgp_community.add((123,888));
}

This is ugly, but if you have little count of communities this is not annoying
solution.
