Merging attachments with PDF forms

Content loss can occur if two or more identical PDF forms are appended.

Appending two or more PDF documents with same form fields causes confusion as there can be only one field with given field name.
Other field with same name will either be ignored or have value as first field.

Possible solution to this issue would be to create a PDF package (portfolio) from PDF attachments.
Unfortunately, SWING PDF Converter does not support this functionality using the toolbar icon.

It would be possible to develop required functionality using SWING PDF Converter API.
