DDJ SX2 Rekordbox Slicer Sampler Capture

Hello I was reading the Manuel for rekordbox to try and figure out how to capture the slicer loop to sampler on the ddj sx2. Tried various shift and button combos to create the sample capture but I have not succeeded in doing so. I thought I could just be in slicer mode loop then press shift and record and it would add to my sample bank. I tried other ways but can't seem to find out how.
