Hi,
This should be fairly straight forward. Add a new variable to your pipeline. This variable should be use be a Record Reference List of the same record your trying to append. Once you have that record reference, append to record to your record list using the built-in service pub.list:appendToRecordList in WmPublic. Map the proper variables and your set.
Update back here if you have any problems.
HTH,
Jim
