Tree structure- Grasshopper

Hi, I know this maybe basic but i am sruggling to find a simple solution. Is there any way to distribute items in first branch (i.e. {0}) between below branches? This is more clear in snippet. Appreciate your input. (4.0 KB)

if you Graft (red circle) your Data_1, then the two merged trees will be matching, so you will end up with the first item of each resulting branch as item from Data_1
