Filr mobile application and cache password setting

Testing Filr and the iPad mobile application and have run into an issue. We might want users to be able to download files to then be accessed when they are offline. We've enabled the downloading of files and set the 'cache users password' option. The user can login while offline and access their downloaded files, this is fine. The strange part is that setting the 'cache users password' setting seems to enable the 'save password' feature on the mobile application and there doesn't seem to be a way to cache the password, but leave the 'save password' feature disabled.

I really don't want to have the mobile device password the only thing between a hacker and our data in Filr. Is there a way to cache the users password for offline access and still force them to enter the Filr password everytime?
