Polygon/Box/Rectangle annotation/highlight of a curve with timeseries x-axis

Is there a way to overlay or annotate a rectangle on a curve with a timeseries x-axis?

A possible use case would be highlighting weekends on a timeseries plot.

This question on Stack Overflow covers the use case I am thinking about.

Can a hv.Bounds element be filled? I would find it easier to use the Bounds API that allows specifying the location of the corners rather than the Box API that requires the location of the box with the size or aspect ratio.

It looks like Bokeh’s BoxAnnotation would be one way to do it, but I am thinking there may be a way to do this in Holoviews.

I’m away from my computer with Holoviews installed at the moment. I’ll try to come back to this with some example code.
