Custom QDropAction Label?

In my project, I want the user to be able to drag and drop a file onto my program and have it open as if they "browsed" for the file.

Here's my code:

void MainWindow::dragEnterEvent(QDragEnterEvent *event)
{
    if (event->mimeData()->hasUrls())
    {
        if(event->mimeData()->urls().size() == 1)
        {
            QFileInfo inputFile = event->mimeData()->urls().at(0).toLocalFile();
            if(inputFile.suffix() == "dat")
            {
                event->acceptProposedAction();
            }
        }
    }
}

void MainWindow::dropEvent(QDropEvent* event)
{
    inputPath = event->mimeData()->urls().at(0).toLocalFile();
    on_actionOpen_Savegame_triggered();
}

Everything works as I need it to, except the drop action says "Copy" when the user is about to drop the file.

I can change the QDropAction to either Copy, Move, Link, or Ignore, but not Open... Is there anyway I can either remove the text saying "Copy" or just change it to say "Open"
