Free warp - don't compress to the right of the tab?

I want to draw two Warp Tabs and stretch the section of audio in between - but not affect the tempo of the audio to the right of the section.
The right end of the audio would need to move further to the right.

Unfortunately, the total length of the audio stays the same because the right end is fixed.

I could do this in the main Project Window using the scissors tool and time stretching, but it would be far easier with Free Warp.

Thanks for your help.
