How to change default notch

edit

How to change the default notch type from simple notch to custom notch When we import or create notches (for example, covering notches from another software or creating seam notches), the system automatically sets the notch type to simple notch. If we want a different notch type, we currently have to change each notch manually. However, even after making these adjustments, when we use "Work with Sewing Line" to modify something, the notch type automatically resets back to simple notch. Question: How can we change the default notch setting so that when we create notches (either for seams or from imported files), they are automatically created with our preferred notch type instead of reverting to the simple notch?
