Struggling to isolate one end of a metachain and am hoping someone can point me in the right direction.

Diagram Example:

Metachain example:

From this point how would I only get one of the ordered set values? Because in this instance both sides are source and target. 

When looking at the table it outputs this:

The sending role is metachain to only display one instance because I still couldn't figure out how to isolate it to ordered set 1. The same with receiving role. The sending system resource is blank because I modified the metachain to show what I am wanting. Otherwise it looks exactly like Receiving System Resource. 

I assume I probably need to further create an operation, but I honestly have no clue after spending quite a bit of time.

Also is there documentation that details what exactly all the options in the properties drop down actually do or implied what they can be used for instead of just memorizing the options from the evaluation output?

Edit: Metachain for receiving system resource
