Two ideas. First, if the feature ID is going to stay constant, try saving the relations to a text file and then using the mapkey to load the relations into the relations from the text file. This will prevent you from typing anything. (Just make sure you press the check box to verify them.) Alternately you could create the analysis feature and then add it to a UDF. This will work well if both the feature the parameter is in and the feature being referenced are both placed by the UDF.
