Hi,

You can use a combination of a choice button with an embedded window and
a local pv in order to get a reasonable effect. I've attached some
example edl files and a screenshot. It probably won't look as good as
Matthew's suggestion, but it is easy to maintain (not so many grouped
and invisible widgets to drag around the screen)

Many thanks,
