Co Client Engagement

Co Client Engagement

The engagement section only has one set of fields to capture risk tolerance, investment objective, etc.  Often though, a record is a married couple.  Once spouse might have a high risk tolerance, while the other is quite low.  This leaves either the choice of averaging the two or creating separate user fields for the co-client that does not appear in the engagement section.  Seems inconvenient and clunky.  How can I add a co-client area in the engagement area for streamlined efficiency?
