ProxyJump/Multi-hop ability?

I'm wondering if it's possible (and if so, how) to use this cli like you would ssh ProxyJump. Specifically:

- I have **HOST A**, an ec2 in a private subnet (cannot allocate a public IP)
- I have **HOST B**, a bastion host in a public subnet of the same VPC as HOST A
- I want to be able to use `mssh` on a local developer's machine to ssh into HOST A via HOST B
- I would need both hops logged to CloudTrail for auditing (because the reason HOST A is private is because it has access to more sensitive information)
