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 ...
