Currently, there are two possible options to copy the production data to the sandbox instance:

• Full data copy, which will overwrite all data on the sandbox, or
• Selective data copy where the tool will copy only the selected projects/spaces from the Production to the sandbox.

1. In the full data copy, everything will be overwritten.
2. To copy a project or space from the production instance to the sandbox using Selective data copy, it's necessary to first delete the project/space from the sandbox and then run the data copy.

It would be great if there were an option to perform an incremental sandbox data copy with selective mode, where the customers could choose the desired project/space and copy only the new data (work items, Confluence pages) to the existing sandbox project/space.
