I'm going to go ahead and guess: development time/costs. Such an app requires developing a multi-platform application to produce these envelopes as well as expanding on the maintenance menu to add other functions (currently only used for firmware updates) for data upload. Development costs get translated into the final price we pay.

Don't get me wrong, I agree that such function would send Zadar into the heavens, but looks like it wasn't in store for us just yet. Not to worry, there's plenty of interesting waveforms on the existing software and plenty of ways to turn those back on themselves and get what you want... or even better, a happy surprise :-)
