I have a wild idea but maybe you can check with the vendor if it can be done.
1) Create a table that will hold only the other fields. 2) Create a second table that will have the same PK and long raw field. 3) Create a view that will combine them by the PK. 4) Since I am not sure in a view with join is updateable you can create instead of trigger that will allow update to the view. >From the program view it will access one table and you can partition the first table.
