How to ease toward clamp range limit

I am building a controller with a limited range of movement. basically, the character can only move in a 30-degree arc from the centre using pitch and roll.
I’m using Clamp angle to stop the character from rotating beyond these limits. However, when the character reaches the -30 or 30 limits the stop is far too sudden and jolting.
I want to build a blueprint to ease or soften the last 10 degrees into a soft stop. I’ve looked at ease and interpolation but I’m struggling to make them work with the Clamp angle mode.
can anyone advise me on how soften the end of a rotation using the clamp angle?
