Yes. When Magical Product Fees creates a fee, it shows up in your Shopify Admin as a regular product (hidden from the storefront). Because it’s a product, you can edit it just like any other item in your catalog.
If you need SKUs for reporting or integrations, here’s how to add one:
In your Shopify Admin, go to Products.
Use the search bar to find your fee product.
Open the product details page.
In the SKU field, enter the identifier you want to use.
Click Save.
The SKU you set will then appear on any order that includes the fee.
