The best workaround I can think of is to ALTER TABLE 1) Make current Primary Key a UNIQUE INDEX instead 2) add an auto_increment INTEGER PK
You may also use an older version for syncing this table (or the complete database or the complete job). However if you have values identical except for lettercase it may result in errors. That is why we removed it. Anyway if you want a copy we will find it for you (I think this was introduced in 7.0, but I have have to check)
