edit subpanel preview

Hello dear Sugar community,

i want to edit the fields(change order) in the subpanel preview:

I know that i can edit the normal preview from the listview in 

/custom/modules/<module>/clients/base/views/preview/preview.php

But changes in this file do not affect the subpanel preview. What do i have to modify to edit this view?

Thank you very much!

Kind regards,

Bernhard
