First, the download location changes, so I have to navigate to a different folder in Primary Destination.
Second, the number sequence changes, typically in three locations. As an example, the last image from job 1 could be JPre2008_000160555, and the next number in job 2 could be JPst2008_000162888. The operative changes in these sequences are re which changes to st, the 0 following the 6 which changes to 2, and 555 which changes to 888.
Of course, later the sequence has to be changed back to JPre2008_000160556, and so forth.
Another change that happens only on some jobs is that Copy RAW and non-RAW needs to be changed to Copy non-RAW only.
If we only had to do one job at a time, we wouldn't have to give it a moment's thought. However, with 4 or 5 changes to be made each time a card from a different job comes in, occasionally an error is made.
