Hello ajalhassan
You can add a tab / fields category to the Student Info screen and then add the fields you need (date, text...).
The only difference is that your data will not be presented in a list like the Immunizations...
Maybe a large text field would be convienient for you? (you can then format text with Markdown and add tables or lists).
Also, custom programs can be designed to be added as tabs, just like the Medical.inc.php
file, check https://www.rosariosis.org/demonstration/Modules.php?modname=Students/StudentFields.php&category_id=new
