Giving a Manufacturer a Rating

[tapiochre]

Hi there

Using 2.0.22a on Joomla! 2.5

Can anyone tell me if it is easy or even possible to add a custom field to a Manufacturer so I can then allow the admin to give the MFR a star rating such as 1 to 5? Perhaps even showing this as star images and allowing the field to be used to sort on best or worst manufacturers? I I have searched but not really found an answer yet.

Hope some kind person has an idea!
