It would be great if there is an option to copy comments while using copy documents functionality in the sales module.

Sometimes user wants to create a new open Purchase document (Quote, Order, Blanket Order, Invoice, Return Order, Credit Memo) based on an existing posted or non-posted sales document (Quote, Blanket Order, Order, Invoice, Return Order, Credit Memo, Posted Receipt, Posted Invoice, Posted Return Shipment, Posted Credit Memo) which may include some comments also. At that time this functionality would provide a quick and efficient way of copying comments from one document to another.
