Is there any direct relationship or linkage between invoices while we are creating the credit memo

we would like to further understand from fusion application end.   

• Whether Fusion AR module supports automatic application of credit memos.
• No direct reference or tagging between AR invoice transactions and associated credit memos in Fusion AR module.

These are key requirements from our stakeholders, hence would like to clarify on the current Fusion AR module behavior regarding credit memo application and linking of AR invoices to guide our approach.
