Format row headers for show on rows matrix individually

I've seen this mentioned before and was told it was "in process" but I have yet to see it happen and I'd like it to go a bit further. This is especially true with really complicated matrix visuals.

It took a lot of work to get this multi level table to work for Finance and it has several levels from Net to Invoiced to Discounts, etc. Normally, you would have the net gross pairs part either Bold or with a bold line above or as a last resort, at least have the grey line go all the way across but it won't do the rows individually.
Amt %
Total OLK UTY Total OLK UTY Total
Returns
Net Total

I'd like to have Net Total be bold and have a line across the top (or on the bottom of the second row) for all fields across.

I'd also like to be able to make the Amt & % total sections diferent colors. A line or a blank space between the two would also be nice. I know a lot of people need this kind of complexity, especially in finance.

It would also be really nice to be able to paste an example in this suggestion :)
