redirect to new domain using a part of the uri

The rule works for this case but will not match if another portion of the url changes. I have listed an example below. Is there a way to add a wildcard match for the data in between the next two slashes and is there also a way to store that next section in another variable? Thanks in advance for any help.

 

 

original supplied url

 

http://subdomain.domain.com/1050/38745/productdata-reviews/reviews.htm

 

here is another url that would be a possibility in this case

 

http://subdomain.domain.com/1050/346687/otherproductdata-reviews/reviews.htm
