Ease multiple properties simultaneously

I would like to have the ability to modify the easing curves of multiple property keyframes of a clip simultaneously. For example, easing the keyframes for both the position and scale of a clip so both easing values are identical. 

My ideal workflow would be to

1. Select desired keyframes
2. Easy Ease the incoming and outgoing velocity of the selected keyframes
3. Adjust the outgoing velocity of the first group of keyframes simultaneously
4. Adjust the incoming velocity of the second group of keyframes simultaneously

This would allow for a consistent change in values between multiple animated properties of a clip, and speed up the process of creating simple animations in Premiere.
