Ok, I'm working on a project where I'm emitting words and letters from a particle network using a Font SOP.  I've created a library of words and letters and the POPnet is pulling from it randomly.  Is there any way to set up a subnet or digital asset that will allow the popnet to emit randomly from letters and words you choose without using a library?  Ideally being able to type in words on a top level to input into the mix?
