Power Headers to create dictionary style headers? Power Headers Forum

I wonder if there is a way to make Power Headers build a header for the following purpose:

I have a list of about 6000 entries – food listed by its brands’ names. For the variable I use the charactyer style "Brand") inside the standard paragraph format (I changed from table to normal text design), where (via nested styles) the first word gets labelled with this charatcer style. The idea is to extend the character style manualle when a brand name is more than the first word.

So far this works fine and I got a header looking like "brandx – brandy".

When a brand contains several sub-items, its name is replaced by a –. So when a – appears I want this entry to be ignored. I guess I can I use a grep formula to replace "–" by ""? 

In the case of a brand name on the first line I and only "–"es following I want only this one name in the header: "brandx".

And if the page begins with a –, the previous name should appear together with the last valid entry of a brand name: "brandw – brandx".

Is it possible to train Power Headers this way?

Thanks,
