Anim notifies play double footstep sound while anims blending

Im place foot step anim notifies in all my animations. Most time all works fine, but when two anims starts blending between, sounds was play from both animations at same time, causing double footstep sound.

I found several ways to solve this problem:

  1. Set anims/blendspaces to one sync group, where notifies was fired only from leader asset.
  2. Change notify trigger weight threshold from default 0.000001 to 0.5 for block notifies fot low weight anims.

But these methods not work for me because:

  1. I use several sync groups in my animation system. Blendings between different sync group anims also causes double sounds.
  2. Trigger weight threshold works with global weight. That means if u blend 10 anims with equal 0.1 blend weight, sounds will disappear because notify need more then 0.5 weight to be executed.

Question: is there any other way to build notifies priority rules? Ideally notifies should executed only from hirest weighted animation in whole anim graph.
