Please remove closed costume companies from the costume vendor list

What specific challenge or problem does this idea solve?

Several costume companies that no longer exist are automatically included on our costume vendor list and we cannot delete them ourselves because they are there by default through Studio Pro.

How should this work?

Liberts, Art Stone, Dansco and Costume Gallery are all still included on our vendor list even though these companies have all gone out of business. It would be great for SP to remove these.

Who will benefit (Admins, Staff, Students)?

This will make entering costumes easier and more accurate for staff and admin.

How will this change impact your daily tasks or overall experience?

Deleting these vendors will help prevent mistakes when entering costumes- mistakes that can sometimes result in costumes being left unordered.
