Xhorse Universal Flip Keys don’t have A Remote Start Button?

Why do none of the universal xhorse flip keys have a remote start button? Is there universal flip key with that option what do you use?
They don’t have but you can change that after programming the remote, go to custom then you change the panic for remote start or trunk if no trunk in car or truck. Then you can remote start.

When you program it will read different like 01 02 03 04 05 just change the panic for start let say panic read 04 and start read 06 just change one for the other and save it back to the key and it should work.
