This sounds like application code. Not one giant UPDATE, but chunked into pieces. Not a TRIGGER to try to do whatever, but app code to achieve the same goal.

An extra column -- Create a 'parallel table' ("vertical partitioning"): Put the PK of the main table, plus that new column in this table. Then do a JOIN when you need it.
