Interpreting footage already in sequence without overlap

Hi!

I'm trying to interpret 60 fps footy to slow to 23.976 fps. The problem is, I've already set I/O points and added the clips to my sequence. Interpreting the footage works fine, but it doesn't ripple expand, it overlaps the clips which obviously is going to be a bit of a problem. Is there a way to set this to ripple edit as I interpret the footage?
