Replicate 'My Contact Details' in the 365 add-in

We use the Xink Client on all our windows desktops.  Our users use the 'Contact Details' window to manage certain aspects of their signature.  This mean that, combined with an intelligent SQL data source, our signatures are pretty much self-managing from an IT perspective.  We'd like to move to the 365 add-in but the lack of a the 'Contact Details ' details prevents this.  Please could this functionality be replicated in the add-in?
