Additional type support for qsTr() in ListElement

It would also be very useful to add script support for the following use case:

ListElement

{ name: qsTr("Go to root"); cost: 2.45; script: <script> }

ListElement

{ name: qsTr("Delete"); cost: 2.45; script: <script> }

ListElement

{ name: qsTr("Search from here"); cost: 2.45; script: <script> }

I also tried to wrap the ListElement contents in a separate QtObject and assign the new object to this. That didn't work either since ListElement cannot contain nested elements.
