Selecting a node using the API

I am developing a UR Cap that has a parent and 3 child nodes. On the parent node, I want to show a summary of the parameters set on the child nodes. I also want to add a button or link that will automatically jump the user to the child node when they click on it. However, I don’t see anything in the API that allows me to set which node is selected? Is this possible?

It is possible to show a summary of the parameters set on the child node. Take a look at this example:

It is the responsibility of the user to select a node in polyScope. Therefore it is not supported to set which node is selected.
