Possibility to add fields on forms delivery note and billing document

Hello,

is there any possibility to have the list of fields that can be added to the forms? In particular, i have to check if i can cover these two requirements

1) Batch, Manufacturing date and expiry date (SLED) on the delivery note forms;

2) Invoice of reference need to be printed on credit memo/debit memo forms, created with reference to an invoice.

Thanks and regards

Daniele
