Pushing Enterprise App to different user or goup

We have setup Mac OS X Server as part of our iPAD deployment through profile manager.
We are trying to push our enterprise app to different user through profile manager,which has different version.
Like Version 1.1 to one user or group and 1.2 to another user or 1.3 to our testing ipad.
For some reason MDM only sees all version as one application and start updating all ipads as soon as we upload the .ipa file.
It erase the old version and keep the new one.AS we want to keep both.
App has same bundle id from our developer team.
Please help is there any work around to overcome this situation?

Thanks
