I am creating a module to management projects with several important dates that i need to show in only one calendar. As far as i know odoo doesn't allow to do this naturally, so based on the idea of the module "supercalendar" for openerp v7.0 i have implemented the following.

The idea is to make a new class with only one date and a field name in which i create a new record for every date contained on each name. Then i can show it on a calendar view, but this, of course, results on more memory usage (even if its not that significant) and the fact that the calendar doesn't show directly the info from my first module.

I wanted to know if there is another way to do this without the need to copy redundant information, or if im on the right way to make it possible.
