Dojo FilteringSelect - disable an item

Question

Is it possible to disable an item from a FilteringSelect using a store?
The documentation shows an example of disabling an item, but only if HTML markup is used, and nothing is mentioned about select widgets using a datastore.
Looking at the source doesn't give any clues either.
If it matters the version of dojo used is 1.9

After viewing at the source code I notice that dijit/form/Select extends from dijit/form/_FormSelectWidget which in fact makes it possible to retrieve and disable options in a select.

dijit/form/FilteringSelect however does not extend from the same widget but rather from a normal dijit/form/MappedTextBox (because of the typing abilities). Because of this, I'm quite sure it's impossible to do it out of the box, using a store or not (I wasn't able to get it to work without a store and didn't find such an example at the reference guide).

If you really need such a feature, I would suggest looking at the code of dijit/form/FilteringSelect , dijit/form/Select and dijit/form/_FormSelectWidget and trying to extend from one (ore multiple ones) and implement these features by yourself. The only question I ask myself is that, if this functionality isn't implemented by default, there might be a reason behind it.
