Another way to avoid thermal relief on inner layers is to: 1. Use area fills, not a plane layer 2. Run a fat trace from a pin, and wind it so it covers the thermal relief. The dangling end of the fat trace may come up as an error in DRC, but is ok 3. You can add thermal pins into large surface mount pads. Just select the pin Doughnut, and place pins in the pad 4. Right click on each thermal pin, and assign it to the same net as the pad. 5. Run fat traces over thermal releif. DRC might complain, but it works. The tool seems to fight putting the trace exactly where I want it, but it sometimes requires outsmarting the tool
