AFAIK there is no way to force several measurements to be performed simultaneously. You can request a specific probe for immediate execution, but that doesn't guarantee that they will all be performed simultaneously or immediately -- the scheduler will have them be performed imminently. As far as I know what it sounds like you're asking for does not currently exist as a possibility.
