Create quick response buttons in UI? (Mapped to F keys)

I’m working on the transition from an old IM system in our office to OpenFire with Spark. We use it primarily for call announcing, though many of the assistants do chat quite a bit. For call announcing, it’s very convenient to have one touch keys that are mapped to the F keys that automatically respond with a preset statement. Anyone implemented something like this with Sparkplug, or think it’s possible? I haven’t found anything so far that would allow me to add buttons on the UI of Spark to implement this . . .
