First of all: I love your plugin. It works for me for weeks now and it´s minor things I struggle with.

One thing I would love to solve and am not sure whether it´s possible or how to do that:
I plan my podcasts and publish every wednesday 3 p.m. Secondline imports and creates a blogpost. That´s fine.

But I want to publish previews and link to the page that is to be published later (i.e. planning posts in Buffer) and would like to have a simpler link like thatsme.com/28 for episode 28. Right now I would have thatsme.com/28-title-of-my-episode which is too error-prone when I want to plan posts before publishing. Is there a way to leave post title out?

The page I need help with: [log in to see the link]
