remote control 15 markers limit

Hi, Im trying to remote control more than 15 markers so that when im playing live I have assigned to one key to one marker and so on with the other markers. But it seems that only 15 markers can be remote controled. Im wrong?
The feature to control with “next marker” or “previous…” dont work for me because I need the freedom to jump to a marker whenever I want to.
thank you very much
