I found no better way to phrase my question but I'll explain it.
I am plotting routes using Network Analyst's VRP. Each collection point has the same colour once the routes are done, but I am assigning different colours to each route and want the collection points to follow the pattern. However, when I choose the "Unique Values" option and sort it by RouteName, the numbers inside the symbols (corresponding to their sequence in the route) disappear. This symbology is automatically created by VRP and I don't know how to do it myself.
Here is how it looks before Unique Values is selected:

Here is what happens once I change the points' colours to their respective routes:

I have found no way to get the numbers back. What am I missing?
Thank you!
