Dismissing the kyrian steward from a macro

[Clarissa]

Not even sure whether I'll pick kyrian but if I do, I'm going to use this:

/cast [nostealth] summon steward
/cast phial of serenity

So that my stack of phials gets toped up whenever I use one, without having to worry about it. One inconvenience is that you then have that annoying npc following you and I haven't found a way to dismiss it without talking to it. I mean it goes in stealth when you do (thankfully) so it's not the biggest inconvenience but it's annoying.

So, does anyone know of a way?

I too am looking for some way to dismiss with a macro. anybody know how?
