Intellij and sbt: How to make intellij to read custom configuration file for my play application tests?

For my test (play framework 2.6 app) I want to use different configuration file.

For this, I've added following line into build.sbt

javaOptions in Test += "-Dconfig.file=conf/application.test.conf"

When I run tests from sbt (sbt test), it works fine, reads the custom configuration file.

But when running tests from Intellij, it ignores this setting and uses application.conf file.

How to force intellij to use this sbt setting?
