Massive url update from test cases

I’am creating some test cases for web UI automation. The system is the same but each client has its own test environment. Ex:,, and so on. Has the tool the capability to change for each test case or from the project directly the url in a massive way accordely with the client? We will design arround 400 test cases, and for each client that we implement the system we should excecute the test.

you can do mapping of environment and do string manipulation to achieve the result.
Please share some details to give you a sample steps for output
