Try custom FFXIV launcher. It has optional plugins for that if you wish. To make them work like in PvP

Just be aware that anything that modifies the game is against the TOS. You probably won't get banned for small things like that, but if you do it's no one's fault but your own.
Never use any macros with the "wait" command in them for combat. The closest you'll get is using macros to replace skills in the hotbar position instead of actually using them.
I.E. Use GCD 1 & it'll replace itself with GCD 2, Use GCD 2 & it'll replace itself with GCD 3, Use GCD 3 & it'll replace itself with GCD. It suffers from macro issues though so I personally dislike doing this. The other problem is that you can't use a macro to replace itself with another macro which is what you're using to swap the GCDs to begin with and that's why you can't truly do what they do in pvp.
It also causes problems for skills/abilities that allow you to skip certain steps in your GCDs.
I wouldn't even use that.
Being a macro it won't use the skill queue. You can swiftcast and raise someone ...swifter by executing it manually.
Even single line macros without wait will have this issue, and it's by design.
