How do I calc a default movement based on a #missing value of "Closing Balance - Input"?

Content

From the info tab of the calculate movements section of the local currency consolidation step:

If a data-point for which a closing balance was previously entered, but is later cleared, any subsequent re-consolidation will not adjust the amount already posted to the default movement. The default movement member amount for each account will be treated as if it has been entered directly by the user.

Has this been done for performance reasons?  Is there a way to work around this? 

We would like to be able reclass movement input on the Data Input source, essentially reversing out what was loaded to and calculated on the Managed Data source.  The reversal is not posted however unless there is a zero input to Closing Balance input (or maybe a block created?).
