Budget Details/Notes Dashboard

Anybody found a good way to create a Dashboard with budget vs actual details where a user could click the budget amount and get more details about what makes up that budget number and the rationale/notes for that budget number? I'm aware of the Excel budget plug-in and PowerPlan (which does allow very detailed budget rationale notes), but how can I bring this useful detail into NXT in a meaningful way? I know that there are “notes” that I can attach to the budget scenario itself or at the account record level, but is there any easy way to get those notes onto a dashboard or to get those notes added from either the plug-in or PowerPlan? I cannot help but think that someone smarter than me has figured this out! ?
