tplvars with multi-dimensional array

Is there any way to define a [onload;tplvars;var..tplvars.name='1.12.27'] but with multi-dimensional array, like this:
[onload;tplvars;var..tplvars.form.name='1.12.27'] and in code to be accesible like this
$test=$TBS->TplVars;
$test[form][name]='something';

Hi,

This is not possible for now.
TplVars assigned in the template can only be a string value stored into a single item in the array $TBS->TplVars.

Thank You
