Set Import Date field to iTunes import date

Hi,

a couple of days ago I tried Traktors Dropbox sync feature. Unfortunately it put ALL the Tracks in itunes into the Traktor library and browsing of tracks for whatever reason started to get laggy / slow.

So I cleared the Traktor collection.
Upon re-import from iTunes so far everything has worked fine except the import date fields. They are pretty much useless now as all songs show up as importet yesterday.

Is there the possibility to set / change the content of the import date field to the correct import date from itunes?

Best regards
Georg
