Changing loop “pre set” values on a cdj & xdj

Hi guys coming from serato and DJing Hip Hop i loves to have my loops setting as 1/4 1/2 1 and so on up to 8 bars. But on my xdj and cdjs 2000 nexus the lowest pre set beat value starts at 1/2.... and goes up to 16 beats The only way I can get a 1/4 loop is by putting on a 1/2 loop and pushing the half cut loop button the shorten it. Is there a way or changing the “pre set loops values at all? Thought it would be just a standard thing but I can’t seem to find it??
