You can apply overlays (one overlay at a time) to the cells of the Relationship Matrix. After you select the required overlay in the 'Overlays' field, you can:

Apply an overlay value or values to a cell that identifies an existing relationship
Create a new relationship in a cell, and immediately apply overlay values to that relationship
Change the overlay values currently applied, or
Remove the overlay from the cell

Notes

You cannot apply different overlays to the matrix at the same time; if you select a different overlay in the 'Overlays' field, any values in the cells revert to either the value set under that overlay, or the direction arrow if no value is set under that overlay
