[NTG-context] avoid resetting of partnumber in appendix

How can I avoid that resetting of the partnumber within the appendices? For example, I have ,----[ Example ] | \starttext | \part{My First Part within Text} | \part{My Second Part within Text} | | \startappendices | \part{My First Part within the Appendix} | | \stopappendices | \stoptext `---- Since I used `resetnumber=no' with `\setuphead[part][...]' \part{My First Part within Text} becomes part 1 and \part{My Second Part within Text} becomes part 2 in the table of contents ... just what I want. Now, I would like to become \part{My First Part within the Appendix} part 3 in the Table of Contents instead of being reset to number 1 again. How do I do this?
