As with any list header change, it would have to be done one list at a time for each list in question. There is no bulk/global replace feature for keyword settings. I would suggest you contact support for assistance.

I would like to enable "Change-Log" in all our mailing lists (~ 600). Is there a way to accomplish that in bulk and, if so, how?
