Automomation to change a Stutus colum if an Item/Pulse has been changed

Trying to set a flag if any columns for a pulse/item have been changed. So any changes then set status to “Item Changed”. Can then set notifications based on the Status change. -
There is a “if Column” changes option but the board has 40+columns (survey board). and potentially there will be addiiotnal columns n the future - Just want “Any Column” change. Is there a way to do this please ?
Have tried to use the system "last updated " column as this would do want I need , but this column is not available in automations (?)
