Setting up automatic crawls with the analyzer is simple to do and will provide us with information to populate the Schema Markup Trend Report. 

In order to setup the automatic crawls the first thing you need to do is make sure to have a website assigned to your project on the homepage of Schema App, like so:

Once this has been done, navigate to the Schema Markup Trend Report via the left-hand menu. When there click on "Settings".

From there you will be able to specify things such as frequency, pages crawled etc. You can make adjustments to these at any time.
