Voice notes attachment in iOS app

I use Asana as my main GTD tool. I was previously using Omnifocus for Mac and iOS. The OF iOS app is really good and I used it often to take quick notes on the go which I later process when I’m at my desk. One feature was being able to record quick voice notes. Really handy when I’m driving (I know… I shouldn’t). I just click new and pick voice note in attachments and record away, the save. Done.
The Asana iOS app is also very nice but this feature is really missing for me. I can take a picture but wouldn’t it be easy to also add voice notes?
