I would like to add a step inside a job which modifies an environment variable (%PATH%) for all following steps in the same job.

If i do this inside the step where i need it, it works. But if i do it in a separate step (which i would like to reuse in other build jobs) it does not work. Makes sense, since i would assume every step runs in its own environment.

Could it be possible to somehow retain changes and reapply them to the environment for later steps? In github actions, individual actions can achieve this by modifying the "path", e.g: https://github.com/microsoft/setup-msbuild/blob/main/src/main.ts#L128

Or am i going about this all wrong, is there another way to achieve something like this already? I actually want to do exactly the same thing as in the example above, add the path to a specific version of msbuild for later build steps
