Somewhat.
First, you can chose between URL and option parsing, that's the last 0
in stream_info_t.
If you change it to 1, something like
bd://track=...:mountpoint=...
should work (if you specify them in-order, the part before the '=' should
not be necessary).
If you don't do that, there is no way to set those options from the
command-line.
Only username, password, hostname, ... options can be set, and
they are determined by doing URL-parsing, i.e. splitting like
bd://user:passwd@host/file
