We have about 400 sermons to publish into the Bible Study list.
I am assuming we will have to match the audio and sermon title, topic, etc...publishing one at a time. There isn't a way to do several at once is there?
Just asking!

Not at the moment, maybe in the future there can be a batch import feature but for now you have to do it one by one. At our church, we add the most recent ones, (after each service), and we also add the ones from the past each time. Its a slow process, but it will eventually get done.

There is a way to do this, but you would need to understand mysql. Originally I had a bunch of studies in a mysql database that I imported into biblestudy when I created it. To do that I needed to match tables and fields between the old db and biblestudy db. It's a complicated process but with some trial and error you can probably do it. With 400 studies it may be worth trying. This is not something that we offer currently, as Eugen said.

Your first step would be to look at the db of biblestudy as installed, then figure out what you need to do to your db to make it match, then just import that into the biblestudy db.
