Thanks! This works great and is exactly what I needed.
For those people who are going to be doing this, back dating something as you post it seems to have avoided triggering at least some of apps that automatically download new episodes (which is good for a new listener introduction, as longtime listeners are unlikely to be interested in it). If you want something to go into everyone’s feed I’d suggest posting it regularly and then back dating it a week later (I did this for my podcast teaser, and that seemed to work fine).
