"edit level" time stretching?

[Carles Vila]

Hi all!
I was wondering if this can be done automatically somehow: Lets say you have a track with lots of small
audio regions. I want to time-strech that track but without processing the audio material with plug-in.
I just want to shift the start of the individual regions by a certain ratio. Example:
region1 starts at 00:00:00:00
region2 starts at 00:00:03:00
region3 starts at 00:00:10:00
Each region is 1 second long
Lets say I want to strech that with a ratio of 2, the result
should be:
region1 starts at 00:00:00:00
region2 starts at 00:00:06:00
region3 starts at 00:00:20:00
Each region should still be 1 sec long

The maths would get a bit more complicated with other ratios, but working with samples instead of TC would help.

Can this be done automatically?
