Memory optimized read method for digital input

Is there an equivalent for AnalogMultiChannelReader.MemoryOptimizedReadWaveform for the digital channel readers (e.g. "DigitalSingleChannelReader.MemoryOptimizedReadMultiSamplePortByte")?

I found a similar question on the forum, but for counters: http://forums.ni.com/t5/Measurement-Studio-for-NET/Is-there-an-equivalent-for-MemoryOptimizedRead-for-counter-input/m-p/1014102/highlight/true#M9305

I'm using DAQmx.NET 14.1.
