Ability to manage bandwith in docker containers, + easier setup to use other containers as network

I would like to have the ability to set bandwith parameters when creating a docker container from the (advanced view) gui. It should be easy to add a tc command into the container.

And/or the ablity to route traffic through another (vpn) container easily.

The reason i wish this is that i could set a tailscale exit node through one of my docker containers when watching iptv on my laptop, thus circumventing geo blocks and managing bandwith when mobile.
