Dynamic Tables (dashboard widget)

I found this because I just tried for the first time to add a table and was floored that I must define every row by hand.  In this case, I have to work around the lack of "bottom N" in graphs so I can watch for devices that have rebooted recently in one place.  I want to put in this table all devices in a group, which seems like a no-brainer from a functionality standpoint.  Having to manually define those and maintain forever is a non-starter.  Can we please get the rows to be enterable as device groups and/or globs, as in other places?

Thanks,
Mark
