Hello. I think I understand the "huge list of names" problem (I am also using subgroups for individual students).
I think you're refering to the "Table of Contents" in the HTML output being long due to the large number of repeated subgroups. You can add the following to the CSS in the timetable's HTML output folder to hide the contents:
ul { display: none; }
(It's not very scientific, but currently the only bulleted list element in the HTML output is the table of contents, so you can hide all lists to achieve what you want.)
