Display New Products by category

I was wondering if it is not at all possible to list products by category, such as doing something like this with the code and then just adding a static link to the new products section:

index.php?main_page=products_new&cPath=91_870_880

cPath=91_870_880 obviously being the category I wish to list when the link is clicked.

Or possibly something like:

index.php?main_page=product_info&cPath=91_870_880&products_id=10062

except where it says products_id if you could use some sort of code to stipulate the last 30 days somehow by products_date_added

Is something like this possible or absolutely not?

Thanks.

Or perhaps a way to sort by a specific model number on the new products page would be perfect, such as the default "Sort by: Model" except to specify which models to list at a time.

Excuse the bump, anyone have any ideas regarding this?

Thanks
