AnimationTree "GroupState Transition Options"

[AxZelAnims]

Hello everyone.
So I've been in love with AnimationTree but as practice, I want to make my AnimationTree organized using Substate Machine (Grouped State Machine) to prevent the "Spider Web/Neural Network" mess

And I'm also abusing playback.travel to jump into an Animation right away, and using a its own transitions to return back to Idle Animation.

For Example....

• Character has Idle Animation in the Root.
• When Jumping, instantly play JumpStart, using playback.Travel("parameters/Jumping/01_1_JumpStart") and it leads to 01_2_Jump_Fall_Loop.
• Upon hitting ground, it transitions to 01_3_Jump_Land and returns to Idle Animation on the root.

Now it works, but sometimes I want to transition a very specific Animation State Machine that is inside a Group to another State Machine that is also inside a Group.

For Example....
"parameters/Running/02_2_RunLoop" to "parameters/Jumping/01_2_Jump_Fall_Loop"

It fires an Error even though it is what I wanted. It seems I should not be doing it like that.

I suggest that there should be an option to pick a State Machine to Transition to when it's a Substate/Grouped Machine just like below :
