I have a POPnet with several streams all of which are currently being selected by bounding shapes.
I would like to find a way to divert the particles to a “default” stream if they are in no others or conversely remove them from the default stream if they are in another stream.

My first thought was to do some group combining but I don't have any such group nodes in POPS that I can tell.

Second thought is that this would be easy to script and this is the help I am hoping to find.

Third option is a VOP approach but for some reason I cant see the groups in the POPvop.
Pretty sure I am doing correct as I can see point groups within a VOP for thew SOP part.

In summary I have two questions.

1. Why cant I access stream groups in POPvop?

2. Is there an elegant Vex approach to test and switch group streams?

After working with this some more it dawns on me that I can accomplish the same thing by organizing the order that the streams are connected. ie any values that are set in the default stream will be overwritten if also being set in another stream that is evaluated later. It appears the connection order is followed.
it is a solution even more elegant that VEX lol
