Passing webservice url dynamically to execute button on interactive form

Hi,

I have been searching and trying various thread on the dynamically passing the url of webservice to a button and calling webservice from different system without any manual changes, but failed to achieve the desired result.

I have a data connection and used it to bind the form element with the importing and exporting parameter of the interface. When I drag and drop the button from the data connection it created a button with execute type of event with the non editable field for the webservice url and interface.

Now when the same form and webservice gets transported to qa and PRD this url will change, hence one option is to update the url manually(which is pretty obvious) solution and other is to pass the url to the button at runtime, Can any one please provide a details and working solution for this or let me know if this is actually possible?

Thanks in advance.
