DL2100 DropBox App Sync


I would like to add my DropBox account to my Dl2100 NAS to sync files. It seems Dropbox files and folders will be synchronized with the Dropbox folder within the Public folder. Is there a way to change the WD NAS Public folder to one of the Shares or other?

I also received a warning "You’re about to link an app that will consume your team’s available upload API quota. For more information, please visit our Help Center. "

I cancelled out as I don’t know exactly what this means…we have plenty of storage to use at DropBox and the NAS data definitely will not fill it up. Can anyone help explain what this warning is and if I should proceed?
