I wouldn't recommend macroing Physick with Embrace together (or any other fairy abilities for that matter)
For the following reasons:
- Physick and Embrace have different recast timers. This will make your healing inconsistent - One time it'll heal for 700 potency worth another time for 400 potency worth.
- You'll have a hard time microing embrace to a secondary target.
- If the Physick is enough to top off the tank, the Embrace will be pure overhealing while another target is missing maybe 200-300 HP (see previous point)

The only macro that could be justified would be rouse with Whispering Dawn. As that seems to be the most commonly used combination. I still prefer to have it seperated for cases when I want to use Rouse, but not Whispering Dawn. Rouse with WD will generate a lot of initial enmity when a new mob appears and will make the job harder for the tank to grab with a 140 potency party-wide HoT right off the bat (Turn 4, for example or Turn 8 dreadnaughts)
