How to Improve Gamma PDF File Naming Using Titles and Subtitles for Better Agent Reference

Hey, we have PDFs being created via Gamma, and then stored to a bank of knowledge. These files need to be referred to easily by agents on our platform, and file names would have a large weighting to allow this. Gamma currently creates these file names by using the title only (we believe) of the presentations it creates. However, sometimes the title is very short/non-descriptive and the subtitle/other headers have the vital context. Therefore, I was wondering if there is a better way to control the file names of the assets created by Gamma. Maybe a parameter we can include while making the generation call to Gamma for the file_name of the asset? That way we can get our ai to come up with the best name for it. Or is there any way that the file_name created by Gamma can use that extra context from the subtitle if the title is short
