Two UOM one column

We are creating a new report and have the need to in two stipulation for the UOM and I’m not entirely sure how to do this. Our product comes in boxes and packs. Right now it is just in boxes so items show up as 15.23 etc. We would like it to show up as 15 / 23 (15 boxes with 23 individuals packs) on hand. Is this possible? I am using AX 2012
