Showing episode number above podcast title

Is there a way to show the number of a podcast above the title? I thought of referencing the post ID, but this is not numeric/sequential so not ideal. I just want to show Episode ’00X’ above each post — you can check out the (static) version here: https://mosaic.ws/lab/rr/
