MessageDialog with configurable buttons / customized button text?

[SeDi]

Hi all,
is it possible to change the Text of the standard buttons in a MessageDialog or to create custom button text like "erase all", "leave in pool" or "remove only"?

Before, I had achieved that by hacking the internal implementation details (parsing children of contentItem, setting different text proprties) like this:

import QtQuick.Dialogs 1.3
MessageDialog {
    id: messageDialogItem
    ...
}
// elsewhere
messageDialogItem.contentItem.children[i].text = newYesToAllText

But this doesn't work any more, probably because the MessageDialog seems to be native on Windows now (see different post).

Thanks!
