Welcome! It's going to be really difficult to communicate "how to's" and collaborate without putting some data into the community's hands to work with. I'd suggest you create a very small, sanitized collection of rows that can be shared via an Excel or Packaged Workbook so the folks here can play.
For what it's worth, I also wouldn't get too attached to the original SSRS layout and functionality. Each product has it's own strengths and weaknesses, so I'd focus on the ideas you're trying to express with the data and let that be your guide. You could end up driving yourself crazy trying to create an exact duplicate when said duplication isn't really necessary anyway.
