Hi v-janeyg-msft 

I have already tried that but while it working for the Table, not working for the List.  In this design I have created List Inside another List. The first list contains all the headers and the second contains the data which is going to be repeated but the solution is not working for me in this case.

While here I can see various options to add Media/Images I haven't seen any option to add RDL file so that I can share the file with you.
