Hello there, @Anonymous.

I want to provide some details on how you can create a vendor lists hat has multiple sub-vendors. Let's get started!

1. Click the List menu.
2. Go to Add/Edit Multiple List Entries window.
3. From the List drop-down, select Vendors.
4. Locate the parent vendor.
5. Click Customize button to select the columns you want to see in the Add/Edit Multiple List Entries window.
6. Here's how to Add entries in the list.
   1. Click in the first empty row at the end of the list and begin making your entries.
   2. Also, you can copy (Ctrl+C) data from Excel and paste (Ctrl+V) it into the Add/Edit Multiple List Entries window.
7. Click Save Changes.

That should do it! Feel free to click the Reply button if you have other questions about adding multiple list of entries. I'm always here to help.
