Is there a way to merge communities from the same prefixes?

please tell me how to do that?

What is your use case for this "somewhat odd" request?


In some cases my users want to use the prefixes from one or two sources
only. So they use route-maps to filter by community.
In my example, if the user wanted to get the prefixes from the peer 1 and
filtered to accept 1:100 only, he loses the prefix 1.1.1.1/32.
