We combine upwards of 20 documents from various formats and sources into a single pdf file. We need a way to append an existing pdf without having to create 20 different pdf documents and then combine or merge into 1 file. Having the ability to append the original pdf when utilizing Acrobat from a print file would save a large amount of time and work. Instead of just a "replace" feature, couldn't there be an "append" feature as well? Many employees within our organization would find this extremely beneficial.
