Here is what I use.

/micon Physick
/ac Physick <mo>
/ac Physick <t>
/pac Embrace <mo>
/pac Embrace <t>

This will make either Eos or Selene cast Embrace on the same target you are healing. You still get the error message though. You can turn that off in chat settings. You con hover over the target or the party list. Either one works. The Embrace CD is also a bit longer than your Physick. Hope this helps.
