My Page Calendar

We've started using redmine to manage our internal projects and are finding it really useful so far.

The one area we would like to tweak is the Calendar on 'My Page'. We'd like to set it so that it only shows a user's own tasks and not everyone's.

Please correct me if I am wrong but this is not possible at the moment and I wondered if this would be possible to update as a plugin? I've read the plugin tutorial, but I'm not really sure where to start.
