secondary category template

Hello,

I’m having a category template, (category_7.php), which shows a selection of my last posts in this category. But when i click on »show all« i would like to show all posts in this category in another template (category_7_second.php.) Is this possible? How to solve this?

Does it make sense to create custom page templates for each category? Or would there be a possibility to make one template that can be used for all secondary »show all« templates?

I hope that’s kind of understandable.

Thanks, Ka
