[Feature]: Create new terminal based on environment variables from another terminal block

[smetroid]

Feature description

I would like to be able to create a new terminal block that basically clones/copies environment variables from a currently opened terminal. Example, I have a terminal where I am connected to a specific Kubernetes cluster and namespace. When I create a new terminal, I would like for these variables to be cloned/copied over to the new terminal, so that the new terminal can be used to look at further Kubernetes information, without having to set these variables again.

Implementation Suggestion

No response

Anything else?

tmux has this feature, which is nice to have, but not sure how to implement it.
