Thank you @Lloyd_Banwart for your quick response!
And I am sure your work around will work all okay for the scenario you assume. But let me give you more details that what exactly my case is and below example might help you to understand my requirements:
I have configure one Aggregate server (locally at the moment) for one of our client and in that we have two forms let say Form 1 and Form 2. In the Collect (Android App). Now what exactly we want is as we have same Server URL for Collect users (ie in ODK collect app General Settings) in Toronto and Ottawa, but we want for Toronto users to get only "Form 1" when we click on "Get Blank Form" not "Form 2". And same case for Ottawa Collect users to get only "Form 2" to fill but not "Form 1".
I hope this time it will help you to understand my requirements but if need more details, please let me know.
Note: On the other end we are okay to see the data as the way it currently display in Submissions in the Aggregate interface.
It would be great help if you could provide any solution for this.
