Controlling P&ID Relation Line color in Canvas CDF

A t the moment, 
CDF Canvas lines for relations ( from P&ID to other document/ assets/ charts/ time series)

are only displayed in purple.

This is an issue when working on big P&ID, and doing RCAs, all lines are purple & become mixed & hard to track - adding complexity to something that is meant to simplify work.
Clients are asking for simplification tools in displaying relation lines , such as:
-The ability to change each line’s color/ thickness/ type, or it would be auto-changes for every new relationship added from P&ID
-Legend tab where one could select what each color represents from relationship lines & is possible to toggle, if one wishes to hide only some relationship lines related to some assets/ time series.

I am not sure if similar idea is published on the hub. but if not, kindly consider it .
