I think this is not possible (maybe with macro).
I used to be a fan of container boxes, but I faced some layout bugs in the web view - especially when using long labels. Therefore today I try to avoid container and use either the minimized icons of the objects or simple buttons and variables.
Please find attached an example of how to use 3 buttons for Market, Region, Industry and a Colorcode controlled by a variable I called vColor=1,2,3
Edited: you can also use show conditional instead of restoring/minimizing the chart-objects.
Hope this helps
