Baffling: Locking SMPTE position of events within a region

Question

So I have a project with lots of tempo changes and MIDI notes recorded to it. I now wish to paste those notes into another project with a fixed tempo (120bpm) but preserve the original positions (reflecting the tempo changes) of the notes. I don't need to have a grid or anything for this region, I just want the notes to appear at the same SMPTE positions as the original project but in a fixed tempo project. I hope this is clear...
So, I figured it's simply a case of selecting the original region in the first project, opening the event list and selecting Functions>Lock SMPTE Position. This does indeed bring up the SMPTE lock symbol next to each note (looks promising). So presumably I can simply paste this region into a new project with a fixed tempo and the notes will appear at the same position as the original region... but alas no. The notes are simply locking to the new project tempo and not preserving the original SMPTE position.
Can someone please advise me if this is the correct way of doing this, or what I'm doing wrong because I cannot get this to work and I can't think of any other way of doing it. Cheers!

Answer 1

SMPTE-Lock everything (including automation) in the old project.
Set the old project's tempo to 120.
Copy-Paste or drag all Regions over to the new Project.
