When using force:mdapi:deploy or any **:deploy really and specifying tests to run, is there no way to specify testSuites? It seems you are only allowed to specify Apex test classes when using the option RunSpecifiedTests. This is very restricting and frustraighting because we maintain all test classes in Suites and could write a simple deploy command to run them if we could specify that. Currently we have to modify the deploy script with a huge list of test classes every time we create or remove a test class.
