At the moment, this is not possible. I believe we did have some
discussion about allowing regular expressions in the style files, but
the approach and necessary syntax seemed somewhat unwieldy.

Also, in this example, I think the "BUS" in "BUS US-127" stands for
"Business Loop", which is distinct from the main "US-127", so dropping
the "BUS" could be potentially misleading.

We certainly seem to have a problem, because it is hard to determine
exactly what is reasonable to display in the highway shields. This can
be quite subjective too. Right now with the code, I am getting things
like "Südring" appearing as shields, which doesn't really seem right.
(This is why I thought about lowering the limit for alpha-only
strings.)

Let's do some more thinking about a flexible solution.

Cheers.
