[FEATURE] Able to highlight the individual mapping line between source block property and destination property of the entity block on Pipes campus

Is your feature request related to a problem? Please describe.
We are the Marklogic customer and use Pipes for our custom mapping flow.
We notice it is very difficult to spot the mapping process from the property of source block to the matching property of entity block if there are many properties in both blocks.
There is not a way to highlight the mapping line individually from source property to destination property.
It is getting worse if there are many steps between the mapping.

Describe the solution you'd like
It will be good to be able to highlight the individual mapping line from the source property to the destination property on the campus of Pipes.
