Support control which buckets specific pod can mount

Is your feature request related to a problem? Please describe.
According to this doc it means I need to authorize the S3 CSI addon which buckets it can mount to pods, the problem is I don't want different pods be able to mount limited set of buckets but not all buckets the addon can mount.

Assuming I have 3 distinct projects hosted in EKS, they have their own set of assets and config files stored in S3. Project B should not mount Project A's bucket and potentially touches or views what are inside.

Describe the solution you'd like in detail
Is it possible to use EKS Pod Identity or allowing us to specific which role to use on mounting S3 buckets annotating in PVC?

Describe alternatives you've considered
