Get WD items that already have some value of a unique ID.
Even if there are none before we start working,
it's still useful to have in case an upload is interrupted
and has to be restarted, or if we later want to enhance
some items. When matching, these should take predecence
over any hardcoded matching files.
The output is a dictionary of ID's and items
that looks like this:
