Audio playback from start

As a musician, all of my audio files are being saved to Dropbox. This is useful because I can listen to the audio on my phone, in my car etc. However, each time that I open an audio file that I listed to earlier, it plays the audio file from where I left it. I'd rather have the option to always play the audio from the start instead because I always manually scroll the play dial to the beginning and this can be dangerous especially in the car with a small playbar like that. I believe that it would also reduce loading times, because Dropbox doesn't have to load the last saved timestamp in order to play it.

At least, the option to choose between starting from the beginning or play audio where from last saved timestamp would be great!
