Hi Samuel (@samuelshannons)!
Indeed there are some examples dealing with thermal analysis involving master/slave definitions.
Few days ago there has been a similar discussion on this subject: Exhaust insulation temperature analysis
For the sake of completeness, please have a look at the following project of a PCB with contact definition: PCB - Transient Analysis
Let me know if that is helpful for your investigations. It would also be nice if you upload your project and share it with us 
All the best and good luck!
