Razer Synapse : work whit games GLOBAL COLD DOWN "GCD"

Many games have a waiting time between the launch of the various commands. is a GLOBAL COLD DOWN my SWTOR has a minimum 1.4 seconds, plus it has 2 different types of commands, the "instants" and "channeled" The ISTANT start when you press it , The CHANELLED start when you press it but stops if you launch another command immediately after .. The question is: How to insert a pause between two commands? I hope I explained myself ...
