MAC 上是否能指定模型的安装位置？我的存储不够

如题？我想把里面涉及到的模型（Checkpoints等）放到外置硬盘，或者整个Comuflowy都安装在外置硬盘上，是否可以？有没有关键步骤的教程指导？谢谢，MAC的存储实在是太贵了……

Look for model loading and storage configuration in the codebase, likely in scripts or config files related to ComfyUI or stable-diffusion. Check for environment variables or settings that define model paths. The goal is to allow users to specify an external drive location for checkpoints and other large files.
