It would be nice for the game to automatically do this, but in the mean time:

Level sync can be macro'd if you have the space for an extra button.

/levelsync

Alternatively for tanks you can do a stance + level sync as well.

/levelsync
/wait
/ac "Iron Will" <me>

*Of course change your stance name to your specified tank, or use them all and let the game toggle through them itself.
