Android keyboard and remapping the CTRL key

I have an Samsung Galaxy 10.1 running Android version 4.1.2. I am using ssh to remotely connect to my main machine which runs Ubuntu 12.04 LTS. Once I am connected I do all my work in emacs 24.3. I also have a bluetooth keyboard. My question is about remapping the Caps Lock key to function as the Ctrl key. I do this with my main machine by changing a setting in the terminal options. I checked the options in juiceSSH and there appears to be no equivalent. Perhaps there is a general way to do this with Android or the Bluetooth Keyboard. How can I remap the Caps Lock character to function as the Ctrl character? If you need more information let me know.
