Mocha proxy workflow in Nuke

What is the proxy workflow for using Mocha Pro OFX in Nuke? The proxy menu is grayed out, and Mocha doesn’t respect the Proxy settings in Nuke.

You can track on a lower resolution file and then connect mocha to a high res file, and in the Mocha UI the shapes are scaled appropriately but exporting a cornerpin to the clipboard leaves the pin locations in the original locations of the smaller file. Hoping the answer isn’t multiple the corner pins to the highres file as a post-process.
