Insert Version should ask for Switchover date

When I want to Bulk Copy an existing version, currently I need to do two steps:

1/ Insert New Version

2/ Do the Bulk Copy

In the first step, the system will create a new version that takes the maximum storage, as you are not asked to specify the switchover date prior to creating the new version. Therefore, due to storage limitations, many times this process fails. 

If the Insert Version form asks to input the switchover date as part of the step, this would work perfectly as it wouldn't require using all the storage.
