How to set category of a post from the iOS share sheet

I wanted to start sharing some media I am listening to from an app called Overcast, so I tried to use the share sheet in the app but the share sheet doesn’t let me specify a category for the post. I can pick the target blog, do some basic formatting, but not the category. Any idea how to do this?

The Share Sheet doesn’t allow this at the moment. The feature is due for an update for a while now.

Alright, I will create a shortcut to post instead. Thanks!
