Using wildcards.

I have a damn big problem (Like I always have). Approximately 900 pages. I do
not want to make them one-by-one.

<!-- start_"N2364-025-KO"_price-->68,80<!-- end-->
<!-- start_"N2364-050-7K"_name--> PRODUCT NAME <--end-->
<!-- start_"N2364-050-7K"_price-->120,00<!-- end-->

I need to rebuild pages to :

<!-- startP_"N2364-025-KO"_price-->68,80<!-- end-->
<!-- startN_"N2364-050-7K"_name--> PRODUCT NAME <--end-->
<!-- startP_"N2364-050-7K"_price-->120,00<!-- end-->

I have tried to find and replace with wildcard, but I cant find the right one
that leaves codename alone.
Find : <!-- start_"[^"]*"_name-->
Replace : <!-- startN_"[WILDCARD]"_name-->
