String/Append mutiple system recordings together in IVR?

Is any method for doing this?

Taking various recordings to make a complete sentence. For example.

for_sales.wav + press_one.wav
for_service + press_two.wav

This is a very basic example, but I am needing to put together an IVR with 40 separate recordings in a similar fashion.


in bash

cat for_sales.wav press_one.wav > new_file.wav

(man cat)

Actually it was in the Recordings menu, but thanks
