iPhone OS 3.2 File Sharing Path

Question

Currently I have this for my file path and file...

NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"Shared\PartyPlanner.sqlite"]];

This allows me to share the file with iTunes, but instead of just having 'PartyPlanner.sqlite' in the 'applicationDocumentsDirectory\Shared'

I have "SharedPartyPlanner.sqlite" in the 'applicationDocumentsDirectory'

is there a cleaner or easier way to get to the shared folder inside of applicationDocumentsDirectory?
