Hi, Eugenio
I think DLJonsson is looking for the same feature I am looking for... a template builder for the details page similar to the one for grids.
A workaround I use sometimes (not very customer / user friendly), is to change the $records_per_page_ar[0] to '1' and disable the other arrays. This leads to a grid with one record only. Now, you can use the results_grid template builder to create an individual template.
Best, Juergen
