How to run two feature files with same tag in the same browser with different credentials

[mansinit]

I have two different feature files, each containing 1 scenario outline and I need to run both with Jenkins tag and the browser is same. The login credentials for the url are different. So is it possible to run both of them at the same time with same tag?

environments {
fb1 {
login.page="www.facebok.com"
login.username = "xyz"
login.password = "xyz1"
}
fb2 {
login.page="www.facebok.com"
login.username = "abc"
login.password = "abc1"
}
}
