Is it possible to "embed" environment variables in global binaries (~/.pixi/bin) and environments?

[thekpaul]

I'm playing around with multiple versions of the same binary by separating them into different environments during pixi global install, and for extra distinction I would also like to set environment variables that would fire up by default for each binary without having to set them as shell aliases or type them in manually every time.

For example, I have different versions of Neovim installed, and for specific environments I would like to set specific NVIM_APPNAME environment variables to ensure that each version uses its own configuration and data directories.

I've tried to see if setting envs.[env-name].activation.env in the global manifest would work, but it didn't. Using the latest version of Pixi (v0.66.0):
