How to disable or enable panels based on drop down value in the dashboard?

[ghostrider]

I have a drop/drill down with 3 values namely:

All,A,B

And there are 2 panels, let's say 1 and 2 which take input in the form of tokenfilter from above drop down. 1 should be displayed and 2 hidden when A is selected. 2 should be displayed and 1 hidden when B is selected. And lastly when All is selected both the panels should be displayed.  Is there a way to achieve this in the panels or dashboard?

Any pointers would be helpful on the same.

In the change handler of the dropdown, set and unset tokens for the whether the panel should be displayed, e.g. displayA and displayB, then use the depends attribute on the panels

<panel depends="$displayA$">

Thanks!! but I dont see any handler in the dropdown settings. Only options I see are below.  I am referring below token in the search queries of the 2 panels. Where do I need to define the "displayA" and "displayB"?

Currently only available in SimpleXML dashboards, not Studio

Ok. Any idea on how to do it in Studio?
