How to concatenate the document outline along with the pdf

[sant527]

In pdftk when i combine pdfs and if the pdfs have document outline (helpful for navigation) they also get concatenated

ALso if i want to dump and later update the outline it can be done in pdftk using

pdftk file.pdf dump_data output dump_data.txt
pdftk file.pdf update_info dump_data.txt output file_index_updated.pdf

Can these three functions be done using stapler. then it will be great

Could you provide some example pdfs for testing?
