Delete uncompressed packages from cube

Hello,

We have a cube with compressed packages and uncompressed. There are several DSOs that are the source data. We need to delete and reload the uncompressed packages from a process chain. The mechanism needs to work similar to selecting the uncompressed packages and deleting to allow a subsequent delta to reload the deleted data. BW is version 7.0.

Something like this:

Any thoughts or suggestions would be appreciated.

Thank you.
