Kintex-7 KC705 Evlaution Board

Hi there, I noted that there are only a few FPGA evaluation boards that is supported for FPGA "Turnkey Solution" in Simulink/HDL Advisor

I was wondering why the Xilinx Kintex-7 KC705 Evaluation Board, which I so popular these days, is not on this list, and whether it is possible to set it also into a "Turnkey Solution," by following the board manager window.

You will note if you launch the FPGA Board Manager in Simulink, that you have two columns, one for "FIL enabled" and one for "Turnkey Enabled". Only very old board are marked as "Yes" (Virtex-6 not too old/bad). Surely one can easily set/change the Virtex-7 into a Turnkey enabled board by customizing it. If so how do one do this and is it easy?

Thanks for the help
