Music selection and 4Stream or GoControl

Hi folks,
I’ve built a boombox with a 2.1 Plate Amp and am using 4Stream control it from a Samsung tablet. I have a bunch of FLAC files in folders on an SD card in my tablet, so in order to select music to play I have to go through browse and then navigate quite slowly to find the files on the card. Is it possible to set-up a short cut to reduce the navigation time to my files, for example in Favourites? I suspect not, therefore am I better off using GoControl instead of 4Stream? It’s not immediately apparent from the descriptions of the app online but it does seem to offer a better navigation to files.
