Hi Jürgen,
Thank you for your interest in Essential DocIO.
1. I was able to see the problem regarding the auto numbering list is missing from the resultant document. Currently the customized numbering list can not be preserved by DocIO. I have added a bug report regarding this issue with our development team. You can track the live status of this issue here,
Defect #2660 - Problem with preserving customized auto number list.
2. Yes, we do have a support for auto numbering list. But currently we have only support for the default numbering list. I have created a small sample to illustrate this feature. Please take a look at the attached sample and let me know if you have any questions.
We appreciate you to bringing this issue to our attention.
Thanks,
Prabhu
