Setting animation loop end points

I want to set arbitrary loop points within an animation. So for example, if my animation is 10 seconds long I might want to loop from 8 to 9 seconds in.
When I set a loop, I see a "Cycle offset", which allows me to set where the loop starts but not where it ends and even that goes back to the start for the next loop.

I've also searched the docs and found this:article but I cant seem to find the window it refers to.

Thanks!

 

you need to count the time for the fadeout start.
https://docs.unity3d.com/ScriptReference/Animator.CrossFade.html
https://docs.unity3d.com/ScriptReference/Animator.CrossFadeInFixedTime.html

and duplicate the state to loop itself

 

I can simply do this in the state update. However if it keeps re-entering "OnStateEnter()"
Which seems wrong because you are already in that state.
if(stateInfo.normalizedTime >= 0.92f )
animator.Play("STATE", 0, 0.71f);
