Dispatch points into two groups while maintaining their order.

I have a group of points that I am dispatching into two groups with the containment tool. The two resulting lists of points have a new order. For example (1,2,3,4,5,6,7) becomes (1,2,3) and (1,2,3,4). I am trying to have the two groups to have the same order, for example (2,3,4) and (1,5,6,7). I am new to grasshopper so I'm not sure if the I've described the problem properly. Also I am having a problem uploading this question so I'm going to try it without the attached files.

Thanks

David

Thanks, I think that command is only in version 9, I'll have to update and give it a try.

yea, sift does it, replacing items not there with null. To keep list order, then you can operate each list separate and bring back together with combine.
