Show mix of Dimensions and Segments in Freeform Table Rows

[#1]

I love how currently you can have rows from multiple dimensions in Workspace Freeform tables. However it would be useful if we could also mix in segment rows with dimensions, as we quite often have to use segments to get to the view we require. For example today I had a table showing line level data for a list of custom products. I also wanted to show the total numbers for that custom list, which would require a segment (e.g. summing visits for individual products to get to a visit number for the while range is incorrect, so requires a segment to get a de-duplicated view of 'Visit where any of products ABCDE existed').
