Flexslider pagination

Hi all,

I'm trying to customize the flex-control-paging that's dynamically created by Flexslider.
Currently it's just filled with the amount of slides I have (eg. 1 2 3 4 5 6 7).
Is it possible to change this to 1 2 3 ... 7?
The Google-search I did didn't get me anywhere...

Thanks in advance
