Describe the solution you'd like

Add 4 splash screens and sound into the menu's model.

Describe alternatives you've considered

I have two hobbies, plane and boat. I use a tx16s MkII and I have modified my splash screen and my welcome sound. My sound say, 'Welcome Pierre, I wish you a good fly' But when I use my boat, I should like to have another welcome sound and another splash screen. My idea would be to have a new option into the model menu for that. 4 possibilies would be welcome.
