Sound markup/insertion

[fridgehead]

This may already be possible (but i cant see how from docs/source), but is there a way for piper to process "tags" and insert a predefined wav/m4a file?
For example: My HASS LLM can insert a tag when it thinks its being funny and i'd like piper to be able to play a rimshot file when it encounters the tag
There are probably more serious uses for this :)
