Self hosted pip repository

I tried to create a self-hosted pip repository to host pip packages in my cloud server. to clone all the pip packages I used the Bandersnatch mirror command but it was cloning data more than 500GB, I don't need that many packages. We need pip repos for IoT devices like GPIO, requests, Redis, and flask.

I just wanted to know is there any way to filter the pip packages which we are mirroring using the Bandersnatch mirror command.

Please help me out with this.
