other than free form?
Here’s how one developer created variables to create templates for users to name files
Wrapto: Wrapper for Capto for Tablo
–filename - Format filenames using template variables like:
%D - datetime (YYYY-MM-DD HH:MM)
%d - date (YYYY-MM-DD)
%i - Tablo file ID
%s - Season number (zero-padding intact)
%e - Episode number (zero-padding intact)
%n - Show name
%t - Episode title
APL Tablo has something similar, albeit limited. I don’t recall if Tablo RIpper has any flexability and I konw SurLaTablo lets you do more than you’ll ever know
