Hi --
If I understand correctly, you are submitting to 4 different lists?
If so, you are going to need 4 mappings and 4 Submit data connections that use the UpdateListItems method of the lists webservice -- each Submit connection will use a different mapping for the parameters.
If, instead, you are saying you want to submit some non-repeating data with your repeating data (that is, your three repeating tables submit to different lists, but also submit some non-repeating data to the same lists) you can manually add the higher level nodes when mapping. You'll map for repeating, then manually enter a relative XPath to the non-repeating field. Including screen shots of my schema tree and my manual addition of a field.
