Allow Apps to Write to SD Without Root?

Hello, I was wondering if anyone had found a way to allows apps installed on the BLU R1 HD to write to the SD card? I've always had bad luck with rooting phones in the past and I do my best to avoid it, so I'd prefer to do it without rooting the phone. I just want to keep podcasts and the like on my SD card rather than on the limited internal storage 8/
