BUG: pxAnyPicker able to select values which are not in leaf node

I have a multi hierarchy data page which i used in a AnyPicker control. Ideally only the last element in the hierarchy should be selectable. However, we are select the parent element as well using + icon, as shown below.

Is there a way that we can configure that + to be displayed only for last nodes (which does not have child elements).

@Avinash.Haridasu Observed that if we set property pyIsParentSelectable we’ll not be allowed to select parent items.
