Be able to store WeakAuras macros in GS-E addons

I think this may be possible. From https://github.com/WeakAuras/WeakAuras2/edit/master/Transmission.lua

local WeakAuras = WeakAuras;

if WeakAuras then
WeakAuras.ImportString(str)
end

I cant do this as cleaning as I had hoped.

What will do instead is include a section in the macro definition for Weak Auras.

Sequence["name"] = 
  Author = "Author",
  WeakAuras = {
    "WAString1",
    "WAString2"
  },
  MacroVersions= {
   ...
  }
}

Is there something new to this?
How can this be implemented actually?

The + button loads the WA
The - button deletes this WA from the macro.
