Why OKS Credit generates multiple AR Lines if Terminating Line with multiple sub-lines

Scenario:  Have a single line contract with multiple sub-lines that has been Activated and Invoiced (with Summary transaction so only 1 Invoice Line regardless of the number of sub-lines).  Client decides to terminate the contract OR contract line = result of a separate Credit Memo Line for every sub-line, even though they were a single line when Invoiced.

Question:  Shouldn't the Summary Transactions have applied to the Credit Memo as well?
