Speed ramping

Is there any way that the speed ramping or using the clip key frames when changing speed of the clip can also effect the audo of the clip as well? This is such a simple feature that EVERY other video editor has. Literally even quicktime has this feature. Why is it so hard for Premier Pro to also adjust the audio to match the video clips speed? Am i missing something? Why do i have to cut the audio after changing the video speed even though the audio and video are linked together to make the audio slpw down at the same rate of teh video.
