Grouping Videos on iPhone by Chapter/Season

I have bunch of files which I named so that Infuse will group them based on Seasons/Chapters and episode but that is not happening. I am following below naming convention:
Title_s1e1_VideoTitle.mp4
Title_s1e2_VideoTitle.mp4
Title_s2e1_VideoTitle.mp4
Title_s2e2_VideoTitle.mp4

There isn’t any metadata for these files so I only rely on naming them correctly so that they are grouped into Chapters/Seasons. All these files are showing separately instead of being grouped together.

Please note that there won’t be any album art which can be fetched from some source since these are home videos

Wow, they are wonderful! I will enjoy watching it while writing a new article to my blog
