Run action in sub directory

[Carlgo11]

Hello,
is it possible to run this action inside a sub directory instead of the project's root dir?
An environment variable that specifies the directory to work in would be nice.

I've had a couple other people request this, so will look at adding it.

I've never used any action before. Where is this supposed to go anyway? I thought it was in .github/workflows... but there's already a github-pages.yml. Not sure if adding a main.yml there would do anything??

I'm having trouble with the "Forty" theme if it matters.
