How to disable souring rule, Approved supplier list (ASL) Automatically?

Using "Generate Sourcing Rules and ASLs from Blanket Agreements" program i created sourcing rule, sourcing rule assignment and approved supplier list.

But lets say if the item on the global purchase agreement is end dated then how does the sourcing rule and ASL is corrected? is there a way to automatically remove/disable.

ASL shows start and end date of the blanket header but not the line end date (agreement date) and the ASL is still active.

Doing this manually will be difficult to maintain.
