If I remeber well my original idea few years ago the decision to use just ASN.1 name was because 
the user can use only ASN.1 specification and does not need to know how the field has been renamed.

I do not see using the same filter name for different fields so bad.

E.g. "h245.network" filter simply shows you all packets containig any IP address.
If you need any exact address you can simply filter "h245.network == 10.77.88.162" or "h245.network == 1:2:3::7:8:9"
If you need just multicat address the "h245.multicastAddress" can be used.

But I can see no problem to introduce new directive #.FILTER_RENAME if renamed fields are more suitable for users.

Best regards,
  Tomas
