I agree with this suggestion - this is an important element that seems to have been overlooked.

Well I figured this one out.  The imported data did not have a category or description field either, and when those were included, the "OK" button became active again.  But I have a followup question - I know you can select multiple records and edit the data in particular fields for all at them all in one go, but it appears you cannot assign them all to a particular room at the same time.  Am I missing something?
