Animation Transition replicas

Lets say I have 30 Animation attacks for different weapons. They will have the EXACT same transitions to a few certain states. How can I transition all of these animation attacks to lets say “IdleWalkRun” or “Crouch”.

Do I have to go one by one by one by one, thirty times to make the same transition? I notice in a lot of anim controllers I have bought, that is what they do.
