Change track tempo without affecting track region placement

I have a song with 24 audio tracks recorded at a tempo of 242. I'd like to change the track tempo to 121 (half the tempo) without impacting the audio tracks in any way.

Here's what I've done so far:

• Selected all tracks and turned the flex and follow setting to off.
• Set the tempo change setting to "Keep".
• Changed the tempo from 242 to 121.

What I end up with is audio that absolutely sounds right and follows the new tempo, but with newly created gaps in the spaces between track regions. I assume the software is behaving correctly, so I'm not saying something is wrong. I'm just asking for advice on how I might collapse the track regions back together (eliminate the newly created empty spaces) without having to drag each region one by one?

Here is a screen shot before and after the tempo change.
