.rpt Inspector 3.1 Enterprise Suite can help without you needing to upgrade your Enterprise environment -- if you don't mind using a 3rd party tool.
When you open a report that is stored in your enterprise environment, .rpt Inspector Enterprise Suite automatically retrieves all the associated meta data with it. The meta data includes the instances and schedules, etc.
One of the options available (on the "Instances" tab) if you right click on a failed or success instance (or even a bunch of selected instances) a popup menu will come up. There you'll see a sub-menu called "Schedule". In this "Schedule" sub-menu you'll see an item called "Reprocess".
So if you choose this, it will ask you whether you want to run it as-is (using all the existing settings of how the instance was run -- same parameters, same destinations, same formats, same database, etc.) or if you want to modify some or all of the existing information. If you choose to modify then you'll be presented with a CMC like dialog that contains tabs called "Schedule" | "Database" | "Destinations" | "Formats" | "Process" | "Parameters", etc. which will show you the existing info in the instance which you can change.
And this will result in a "Run Now" on an existing instance (it create a new instance from the one you run it on for your historical and archiving purposes). But the whole process takes a few seconds really.
There's also a tool in there to modify schedules of recurring instances without having to delete them and recreate them (like you do currently in CE & BO XI), and a lot of other tools.
