Converting a tree to a list by summing each branch

I have a tree of boolean information. I want a list that if any branch is true the list is true. I created a cluster that does this, it just seems inefficient I would think there has to be a command within grasshopper that does this automatically.

Could you use mass addition? If the result is greater than zero, the list contains at least one true value. Is that what you are after? If not, can you post a file that might help explain further?

Bingo. Thank you
