Is your feature request related to a problem? Please describe.
hier.import only either unwinds or deleteallelements prior to import. There should also be a additive or "don't touch the dimension before import" mode similar to other processes which woudl be encoded by pUnwind=-1
Describe the solution you'd like
Support pUnwind= -1 for do nothing as far as unwind/clear pre-actions.

supported with pUnwind=2 for "do nothing"
