Generating a Schedule

Hello,

I was wondering, if a plugin exists, which can do the following.

I am currently working on a site for a convention. On this site there is a schedule with all the events, which are going to take place.

What I want is a plugin, which can generate a personal schedule for users who are visiting the convention.

So when the browse through the schedule of the whole convention and see an event they like, there should be a button “add to my personal schedule” or something like that. When they are done, they should be able to klick “show my schedule” which leads to the schedule the generated to show up, so that it can be printed.

Is there something able to do this?
