How can I define a category for attachment in documents

Hello

I can't upload a file in a opened incident.

The unique alternative that I found was give the admin permissions to the user (No, I won't do it), or add the user to the permissions of the incident, in documents, but if I do it, I will need to do it in all incidents, one by one.

I need a solution to all incidents. I though in create a document category and give the permission to all users, but the problem is in how I can define this new category as Default.

I need to define to that attachment will go to the new category and won't create a category based in the ProcessID.

I didn't search nothing in the Workflow.

Anybody knows a mean to do it?
