If I make a Macro that has that as an icon for Ninjutsu, will it only display the ninjutsu icon or will it still change to show which ninjutsu can be cast once I input mudras?

For example i wanna do something like this:

/micon "Ninjutsu"
/ac "Ninjutsu"
/wait
/ac "Trick Attack"

This is so i can free up a slot for hotbar space (PS4) and it will attempt to cast TA if applicable. But if the Ninjutsu icon doesn't change during mudra input then it defeats the purpose. XD
