In one of my projects, when opening a new PR, it used the wrong envvars, the ones that push my python module to public releases on PyPI, but really are supposed to go to TestPyPI. I would love to be able to choose which envvars are used in a new PR environment, before it is ran on the GitHub PR. It could work, like if you are not on the site at the current time, you would get an email/text notification, or if you are on the site, but in a different project/page, you would get a site notification, if you are in the current project page, you would get a notification icon by either environments or the vars tabs. If you do not go to the page, either after closing the site, or a set timeout of inactivity, or going to a different project page/railway page, it'd act like you are not on the site, or on the railway domain, respectively. Let me know if you understood this...
