It'a great idea to change custom fields with AJAX on entry adding/editing!

But - for example - I have 2 categories in 1 instance - one of them for photomodels (custom fields - age, haircolor etc) and another one for still cameras (custom fields - camera, lens, technical data etc)

When I choose a category on - I can see ALL of custom fields, no matter which category they belong

Question: Is it possible (I have not found these settings in Demo) to show only custom filelds belongs to one and only one category?

Sorry for my English
