inserting web objects dynamically

Does anyone know if you could add a webobject to a slide that has a dynamic url. In other words that would be different each time depending on a variable. So could I create a variable that is created at run-time that is fed into the url of the web object?

I see the url to the webobject is hard coded in  javascript to a file...in my project example it is found here... html5 >> data >> js >> 6qurmYcWU9l

Something like this:

"objects":[{"kind":"webobject","url":"http://www3.hants.gov.uk/emtas-logo.png","html5Url":"http://www3.hants.gov.uk/emtas-logo.png",

Could that hard coded url reference be a text variable that equates to that same url?
