There are no real block files for wireway or DIN rail. These are built parametrically by ACADE at insertion time. The parameters it uses are based on the wddinrl.xls file, along with the selections you make in the dialog.
Using the Stretch PLC tool works fine on wireway, but it *technically* fails on DIN rail. The command doesn't know how to handle the interior graphics there, and things get jumbled up and overlaid with one another. However, I don't let this bother me since there's always a footprint with a wipeout hiding the DIN rail. So, I do confess to using this tool anyway, though it wasn't meant for the purpose.
Also, a general note about dynamic blocks and ACADE: not supported. I mean, you can sometimes find situations where you can make use of dynamic blocks, but they can't be used for any symbol or footprint that contain attribute data. This comes out to probably 99.99% of all the symbols we use. Here's a link to a forum post where Trond chimes in, at the end, with a pretty concise explanation as to why:
