Change primary Works Email From and To Dates

Summary:

We need to be able to update the To Date on the primary Works Email address. Currently for some records its blank (null) and effects some reporting.

Content (please ensure you mask any confidential information):

I dont see anywhere that I can update the To Date, there is no date field that I can amend. The Security console only allows me to update the actual email address. I've included a screen shot to show how the Email address looks within the Person page.
