You can check a current plan Id with currentPlanId and change the src of which is on this plan:
<iframe border="0" src="/scada-vis/trends?id=24" width="984" height="464" frameborder="0"></iframe>
But all of this you can do with Custom Javascript.
You can for example add some Additional class e.g. "Kitchen_Temperature" to the object which is connected to universal widget and then based on this class you can change the src of this widget.
I have similar issue so maybe I will try to create something like this
<iframe border="0" src="/scada-vis/trends?id=24" width="984" height="464" frameborder="0"></iframe>
