Suggestion: Option to Add Custom Grading Company

have an idea for a new feature that could be valuable for collectors and users of your platform. Currently, you support a limited number of grading companies, but there are many (both large and small) grading companies worldwide that are not yet included in your database.

Proposal:
Allow users to add their own grading company with the following functionalities:

• The ability to add a custom link to the grading company's database, including a certification ID (e.g., www.customcarddatabase.com/cert=123456789).
• The option to define and add the grading scale used by the selected company to ensure proper integration with existing price data and filters.

Why is this useful?

• Many grading companies exist, and not all are currently listed on your site.
• Collectors can more easily track and verify certified cards.
• This feature would provide more flexibility and improve the user experience.

I believe this feature would benefit the community and further enhance the value of PriceCharting.
