Wildcards in /upload -

I have done searches and read through the forum and site and can't find this answer. I want to upload all files in a directory that are filtered as PocketInformant_*, but I can't seem to get it to accept wildcards. So for example this works:

"C:\Program Files\WinSCP3\winscp3.exe" PI_Upload /upload PocketInformant_English.ARM.zip PocketInformant_English.ARM.cab /defaults

/upload does not support wildcards and won't support them as it is not its purpose. Use scripting instead.
