Razer keyboard macro question

Hey guys, I have a Razer Blackwidow Chroma v2 using the current Razer Synapse app for my macros. I am trying to come up with a way I can bind my "A" and "D" keys for FPS style games. The idea is to make it so that when I am using "A" to strafe left and push the "D" key the character will either stop moving or start strafing right until the "D" key is released then continue strafing left (and vise versa when starting with a strafe to the right.) Meaning both keys are held down at the same time, or used to stutter step while strafing https://vlc.onl. I know I had a macro to do this back in the 3ed expansion for World of Warcraft long long ago, but that was an internal macro to the game not something specifically setup for my keyboard. Has anyone made something like this before or have an idea how I could set it up either through keybinds or with macros using the Razer Synapse App? Thanks in advance for any information on getting this to work!
