Accessing multiple import file names via DA

HI Guys, 

Is there anyway via a method query or rule in a data adaptor that I can specify parameters to give me all file names related to a workflow. I preferably want all file names in a specific workflow for all years in a data table of columns: (Workflow,Year,Filename). Presumably doable with a dashboard data set rule but Ive never played with the staging engine before! 

Guessing also that its probably a case of looping years and appending tables. 

Thanks,

Tom
