Prospect_list module

I’m generating a report using an entry point and I can’t figure it out how to get the date when a lead/target/contact was added into a target list using beans.

This is the report

and the field that i need to get is the date_modified that is inside of the table ‘prospect_lists_prospects’

since that table is not a module i dont know how to get that information using beans

I never used it, but perhaps it’s the retrieve_relationships function in SugarBean.
