I want to test a project against latest Dotty 0.28 nightly builds, while it requires many dependencies that have last been published for Dotty 0.27.0-RC1. Without going into the question of binary compatibility, is there—for testing purposes, to see if a fix in Dotty applies to the project that previously crashed dotc—a way to specify in build.sbt diverging scala versions for the compiler that's used (I want 0.28.0-...-NIGHTLY) and the dependencies looked up (I want 0.27.0-RC1)?
I do not wish to edit all of libraryDependencies to change % "foo" for % "foo_0.27.0-RC1", but want a global way to enable this behaviour.
