Is there any way to make the recorded script not tired to webpage content?

Hi, 

I am new to LoadRunner. I recorded some scripts with Web-HTTP/HTMLfor Web service performance test. But out web service pages have changed very offen. Each time the pages changed,  then my test scripts got broken, I need to redo the recording and parametizing, correlation, etc,  I am wondering if there is anyway, to untired script from web page content?

Thanks!
