Progress display with multiple progress bars each having a label above the progress bar

[elgonzo]

Is it possible to have a live progress display with multiple progress bars that each have a TextPath label above the respective progress bar? Kinda like in this mock-up image:

Side note: I was experimenting with a custom render hook - inspired by this Progress example - which would recreate the grid underlying the progress display, but i couldn't figure out how to make a grid row span multiple columns. And using separate Grid's for each progress bar isn't working either, as then the grid columns of each progress bar row are sized independently from those of the other progress bars :-(
