I want to retain (or resurrect) the redline From-To markup for any and all of the CPs that have been applied to a single requirement.
The out-of-the-box Change Proposal module does not retain the original "From" values for the attributes under CP control. So after the CP is "Applied" there is no mechanism to show the "From-To" for that particular change.
Is there a strategy that typically gets used for this application? (Is this a typical application?)
Add attributes to the CP module to store the original values?
Search the target object history for the last change to the attribute value prior to the CP create date?
Find the previous change in the CP module and use that "To" value as the next "From" ?
