How to specify push (P) target remote?

[proofer]

I have two remotes, which lazygit seems to have picked up from .git/config, which is fine. They are upstream and origin. origin is my repo, and upstream is someone else's that I forked. I want to do all my pushes to origin. But lazygit wants to do them to upstream. I can't figure out how to change the push target.

Are the pushes for all branches or just for one branch?

If the former, you could just run a custom command through :, e.g. :git push --all origin.

If the latter, you can set the upstream of a branch by pressing u on it (Local Branches panel).
