Manager installs pre-release torch packages, then undoes the installation

Given that I use a Mac, I prefer to run the torch/audio/vision nightlies to stay up to date with improvements and fixes. However, starting a few months ago, the installation became much more difficult using ComfyUI-Manager.

To do the installation, I copy the text `--pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cpu` into Manager's package installation dialog and restart the server. Manager properly downloads the newest versions and places them in the site-packages folder.

However, recently, when ComfyUI starts again, there is a significant pause. The prerelease packages are removed and the newest release versions are installed instead. This will keep happening if I rely on Manager's installation routine. In order to get the prerelease versions properly installed, I now need to move their folders out of site-packages between when Manager installs them and uninstalls them. Once ComfyUI starts with the release PyTorch packages, I then manually delete them, move the prerelease folders back in to site-packages, and restart the server again. This is cumbersome and often requires several attempts.

Is there anything that can be done to fix this?
