Complicated reports with KoolReport

[krzysztofpro]

Hi! I'm in case to create a little bit complicated than normal report from Espo Meetings. In attachement expected appearance of the report. Now I know that is impossible to generate that report from Espo (correct me if I'm wrong), so i wanna implement KoolReport (https://www.koolreport.com/docs/) as add-on. There i can generate report using MySQL connection etc. So the first question is, how can i create subpage with some html and php in Espo with link in side menu (like to entities)?

If I can create this subpage with KoolReport code, i'm in home with that.

I think, it is possible in espoCRM. As I understand your idea, I would do the following:
Create a custom entity for "Meeting Invoice", there you relate to contacts and meetings. This way you get the data from the meetings and do the calculation in that custom entity.
After that create a PDF template from the custom entity.
