I thought about it for a bit but I think it's not the right thing to do.
The via diameter/drill were setup as pairs of dimensions, they should be
used a such. Otherwise one could select a larger drill than via diameter
which would be weird for predefined values (one can always enter the
values by hand to get the effect ;-).

Anyway, I also experimented with the implementation of such a behaviour,
I don't think it can be made to work. The problem is in updating the
dropbox itself to a different value than is in its value list. This
leads to the control resetting its internal position in the value list
which makes scrolling by up/down key through the values impossible. I
have no idea what weird behaviour could emerge on Windows or Mac.

That is ultimately the reason there is now a standard dropdown list to
select from.
