Hello and welcome to the forum!

Unfortunately I cannot answer this question either. But there is an alternative way to get the requested results: offline.
Some software is able to filter .pbf or .o5m files. I am not sure if Osmosis is able to deal with wildcards, but osmfilter surely is.

Therefore you could:

  • download the regional .pbf file
  • convert it to .o5m format (osmconvert)
  • filter it with osmfilter
