Is possible to choose the time when a state changes, during a transition in Animator?

Hi,

I’m implementing a controller for my character. Using animator, I can see that the moment when a state changes to another is at the end of their transition. My question is:

I can change this moment to, for example, the beginning of the transition?

I have some events that I want to fire at the same moment the transition starts, and I don’t want to replicate part of these transitions in my own automaton script, if I can avoid it. My idea is catch the time when the value of "currentBaseStateInfo.nameHash" changes to launch events between states.

I guess that it cannot be, but worth seeing suggestions that you can offer me :D

Thank you all!
