Possible to change the Cross Reference of Compensation Plan that has been posted back.

Content

This is a really odd question, I know. Bear with me.

I would like to change the cross reference in a compensation plan that was posted back last year.  So far I have not been able to do it.

I have check the Subject to Refresh and unchecked it in the column I want to edit.  I have ensured that the cycle worksheet editable dates are appropriate.  I have run the refresh multiple times in various ways. 

I know this is a long shot but I thought I would at least ask.  Aside from pulling the posted data, is there any way to edit a submitted worksheet??
