Crystal Repository

Hello:

I have some questions...

1- In Crystal exists a reports repository??? I want to have a reports repository that I upload a report, make some executions in diferent days and, if I change my report (update version), I continue have that executions and I can consult it (even the report is changed). Is that possible??? If yes, How can I do??

2- How can create a repository??? (I don't find it anywhere)

I have installed Crystal Reports XI and CMS
