Default LightWave - Keyframe looping... but not from the beginning

The solution eludes me. I have no doubt that a simple, elegant method exists, but I'll be damned if I can figure it out.

Very simply, I am creating a "traveling strobe" effect by incrementally positioning a luminance plate. As the plate moves, some bulbs go ON and others go OFF. This animation has a natural starting point, but it eventually reaches a state where the luminance plate needs to return to where it was at frame 24--not frame zero!

The looping region is therefore a subset of the generated animation:

The familiar "repeated" switch cannot be used here, because LW assumes I need to repeat frames 0 through 36. How does one loop a specified range of keyframes?

Do it as a separate animation file.

Render the frames (not the animation) from frame 1 to 24 (or whatever). Save a copy of the scene file; move the motion envelope to the left so that frame 24 becomes frame 0. Then tell LW to render the rest of the frames, starting at frame 24 (or whereever you left off). Once all frames are rendered, then you can load the sequence into Layout and render it out as an animation.

I know it's nice to be able to do everything in one rendering session, but 3D software doesn't always allow that. Even the big VFX houses do scenes in parts and combine it all together later.
Those who say it can't be done,
should stop interrupting those of us who are busy doing it!
