Cant move Blend tree sub nodes

So I have a Blend tree, it blends between three other blend trees. Problem is I cant move those three blend tree nodes so they are overlapping each other . Is there any way to move nodes in blend tree?

 

Having this seem issue, did you ever figure it out? I have seen other people's blend tree's and it seems like they were able to move the nodes around somehow to space them apart better.

Update: looks like after awhile Unity just organizes them for you, very strange. It seems inconsistent as to when Unity decides to organize the nodes *shrug*.
