Vivi how would that play out in an automated process, though? Doesn't seem like the flow would know WHICH program to change the program data for. Or am I missing something?
There is a flow step action called "Change Program Data" where you can change the success to either true or false, and change the success date. You could certainly have a trigger looking for a lead becoming known and changing their success and success date in your different content programs to true and to today's date (or any other date).
