Use global variable for url parameter in widget config

I'm not sure I'm best articulating the question or the path I'm trying to go down here but I'm wondering about having a configurable value that can be concatenated to a url parameter in a widget config. I have a case where a portion of a url changes based on if the application is a development or production version. As opposed to having a dev and prod config for each widget that has different dev and prod urls, I'd like to just have a configurable value I can set that will be concatenated to the rest of whatever url value is in the widget config. I was thinking, I could set a global variable when the application loads maybe something like var PrdOrDev = 'PartOfUrlThatMakesItPrdorDev' and then in my widget config change the url parameter to "${MyDeploymentVersion}/moreurl/arcgis/rest/blah/blh/blah" and then modify processUrlInWidgetConfig in utils.js to handle url.startWith('${MyDeploymentVersion}) by replacing it with window.PrdOrDev. For anyone that's followed me this far, is this a proper track or is it completely off the rails?

Andrew,

That is a viable path. The processUrlInWidgetConfig method is not used be default in the widget though so you would have to modify each widget to use this method be handling a url.

Thanks Robert. I hadn't thought of that. In your opinion, is maintaining DEV/PROD config files for each widget the more prudent approach?
