How to get all the auth objects into a role which are belong to specific auth class

Hi Team,

I have a requirement that, create a role with all the authorization objects which belongs to FI module.

So in FI authorization class we have total 247 authorization objects. Now how I should get these authorization objects into a role directly ? (without using Manually option because it consumes lots of time). Please help me out to solve the issue.

Thanks in advance.
