Blueprint approach to change blend in/out time of AnimMontage ??

Hi, developers,

I’m now trying to tune some animMontages’ blend in time based on the current stance of the player character.
After many tries of web search, I found nothing handy which can modify the blend in/out time for an AnimMontage.

Is there any other approaches? I don’t really want to spawn multiple AnimMontage just to make them different in blend in/out times.

Thank you.

There is a blend out time available in Stop Montage.

Although I wish it could be something done in PlayMontage.
Well, it’s still a workaround, I guess.
