A128 lake water temp

[Natch]

I have two A series MFDs on my Ranger. Always been a Lowrance guy, but the Raymarine MFDs were installed in the boat when I bought it. After a small learning curve, I actually prefer the MFDs over the Lowrance units on my last boat. I have an A127 at the bow with a CPT 100 Transducer on the TM, which provides me with both 2D & Down Vision Sonar. The transducer also provides me with water temp.
At the console, I have an A128 with a shoot through transducer in the bilge for 2D Sonar and a CP200 Module for Side Vision, with the transducer mounted to the jack plate. The CP200 transducer does not provide a water temperature reading and I need it at the console, while running the big motor. How do I add water temp, without adding the CP100 module, which has the water temp sensor??
I can't add another transducer to the unit, so I'm looking for some advise.
Thanks in advance,
