I've created two fields called "Lead Source - First Touch" and "Lead Source Details - First Touch." These fields will be blocked after they have initial info, but I want to also create two fields called "Lead Source - Last Touch" & "Lead Source Details - Last Touch."
Is it possible that once those two fields are locked, if anything attempts to overwrite them, that info gets pushed to their Last Touch equivalents?
EDIT: New to the Community, so if I have put this question in the incorrect area, please do let me know. Appreciated.
