Automate changing the title of a document file in Workflow for iOS

My church records and posts there sermons online. In workflow for iOS, is it possible to create an automation that would grab the title of the sermon from an excel spread sheet or google sheets based on that Sunday’s date and change the podcast file name to the sermon title? The podcast file is stored on Dropbox.

I am open to using something else other than excel or google sheets to store the data.

Thanks for your help!
