We have recently re-launched our website in .aspx. One of new features is the capability to rename our URLs. We can do so either by uploading an excel spreadsheet or on a product-by-product basis via a page on the admin side.

Our current product pages end with something like /pdetails.aspx?subcatid=62&pid=13642. We want to end up with something like /our-product.aspx. Our programmer says that we cannot rename our URLs in batches. For example, we want rename some to /our-product.aspx, while others will remain /pdetails.aspx?subcatid=62&pid=13642 for the time being. He says they all have to renamed at the same time.

Does that sound right? Can anybody think of a way around this?
