You can frag it pretty easy, I do it to my capnella finger leather often. As mentioned, they do slime a bit so removing it from the tank first is a good idea. Take a sharp razor blade or scaple and slice off a branch. The thicker the better. Make sure you have a towel to dry the end and use super glue gel to secure the cut end to a small chunk of LR rubble. Let the glue cure for a few minutes before placing it back into the tank. I suggest placing it in an area of very low flow for a week or two. Finally...sell the corals to local reefers or trade them in at the LFS for credit. This is a very resilient coral and does well when fragged.
