If only I could post a picture.....

Select all desired regions. In batch fades, unclick the "create new fades button" and turn on 'create new fade ins & outs" Set placement to centered, and length to whatever you like, say 500 ms. Set the fade in shape to the hard-in buttsplice shape (top of the column in the pop up). Set the fade out to linear or any of the parabolic shapes. Done!
