Magic Mask & Deliverables to Different Aspect Ratios Workflow

Hi everyone!
Since updating to 21, I've been trying to utilize Magic Mask in my workflows a bit more. However, I've been running into a bit of issues with sending out deliverables that are a different aspect ratio and/or have transforms attached. I was wondering what the best workflow would be to:

A) Have the rendered out magic Mask work at different resolutions (as I normally work at 1080)

and

B) Have that matte render out properly at source Resolution for a 3840x2160p timeline.

For example, I have a clip that is 5764 x 3192, however pic lock is UHD with a transform (zoom = .677) @ Center crop no resizing. To "make it work", I disabled the Transform, swapped the TL to source Res and output the Magic Mask and rendered it in place. Then, switched the TL back to pix lock and adjusted the matte to match the transform. This works on point "B", but when I output a deliverable (which would be source Res + disable sizing and blanking output) , the Matte is obviously off. This becomes a large issue because the client is doing finishing, so I'm looking for the "best of both worlds" so to speak.

Any tips / tricks for client deliverables on magic masks with a different aspect ratio / transforms would be super appreciated!
 
Unfortunately, although the thread is helpful, none of the workflows discussed solved my issue (as my issue is about deliverables of different aspect ratios & editorial changes).

Fortunately, I discussed with an incredible colleague a workflow that DOES work. For anyone in the future who may have the same problem, here's how to get magic mask to work for different aspect ratio sends & deliverables.

-Duplicate your timeline. In this timeline call it "Sequence name - Magic Mask"
-Timeline Setting --> Set to clip's resolution size.
- Disable any transformations on the clip & editorial decisions.
-Create Magic Mask
-After creating Magic Mask, hit the "..." dropdown, export it as an external matte and relink.
-Once relinked, swap to your original timeline.
-Relink the external matte here.
-On the external matte, match the editorial transforms on the sizing options.
-Hit LOCK MATTE.

Now the matte will export properly for deliverable sends of "Disabling output sizing & Rendering source res", while still keeping the editorial decisions via XML.
