How to change the generated filename for App Bundles with Gradle?

Question

So to change the generated APK filename inside gradle android I could do something like:

applicationVariants.output.all {
    outputFileName = "the_file_name_that_i_want.apk"
}

Is there a similar thing for the generated App Bundle file? How can I change the generated App Bundle filename?

As a more generic way to Martin Zeitlers answer the following will listen for added tasks, then insert rename tasks for any bundle* task that gets added.

Just add it to the bottom of your build.gradle file.

Note: It will add more tasks than necessary, but those tasks will be skipped since they don't match any folder. e.g. > Task :app:renameBundleDevelopmentDebugResourcesAab NO-SOURCE

tasks.whenTaskAdded { task ->
    if (task.name.startsWith("bundle")) {
        def renameTaskName = "rename${task.name.capitalize()}Aab"
        def flavor = task.name.substring("bundle".length()).uncapitalize()
        tasks.create(renameTaskName, Copy) {
            def path = "${buildDir}/outputs/bundle/${flavor}/"
            from(path)
            include "app.aab"
            destinationDir file("${buildDir}/outputs/renamedBundle/")
            rename "app.aab", "${flavor}.aab"
        }

        task.finalizedBy(renameTaskName)
    }
}
