It sounds like you are after our BaseUrl
feature. The BaseUrl feature is intended to be used for the same application running on different servers. You only need to alter your "Navigate to" step for the BaseUrl to work.
For example: double click the "Navigate to" step and enter only a forward slash(/) in the NavigateUrl field(see screenshot). Now when you need to execute the test against different Url, just alter the BaseUrl field in "Project Settings->Recording Options" to the desired Url. Note that your application must be structured the same on each server, with only the server name differing.
Let me know if you require additional assistance on this.
