Mecanim jump animation

Hello, I am using Mecanim and I'm trying to make my character jump. I have several different types of jumping, depending on my character move direction (such as jump forward, jump left, etc), so I consider the most comfortable way to fulfil this is to use a blend tree (as I already have done with running). But since I use in-place animation, I'm using three animation clips to implement a jump: jump_start, jump_fall, jump_end. It seems to me that the most comfortable way to control the jump itself is by using the sub-state machine, which would be constructed from those 3 states. The question is: can I somehow implement this scheme, to choose a proper sub-state muchine using a blend-tree? Thanks in advance.
