How to override close reasons, credit methods on Asset Lifecycle defaulted values in Subscription

Summary:

Not able to use different close reasons, credit methods for Subscription covered level termination flowing through Reprocess IB Updates process.

The scenario here is to have ability to select different close reasons and credit methods based on requirement.

Steps followed:
1) Assets are end dated (CustomerAssetEndDate) in Installed Base.
2) Reprocess IB Update is triggered and submitted
3) Corresponding Covered Levels are terminated automatically with the Close Reason, Close Credit Method defaulted in 'Asset Lifecycle Management' in Subscription Rules.

But we need to use different Close reasons and Close credit methods than what is defined in 'Asset Lifecycle Management' in Subscription Rules.(based on the requirement)
