Pivot table - more detailed cell border options / conditional styling

The pivot table currently only allows for cell grid to be on/off.  Ideally it would be good to control row border style individually.

For example: I can have rows with Level 1 in BOLD CAP, Level 2 in Bold mixed case, Level 3 in Normal, and Detail in Italic.  Instead of / in addition to conditionally coloring those rows it would be sleeker to provide border line styling for each of those levels as: very thick, thick, normal, and light dot.  This would reinforce the font styling while enhancing report readability.

If I had a multi-level column structure I'd probably want to have the very thick | thick | normal structure as per above -- or may want to use thick | normal | no border.
