Suppress "Show Solution" in "Speak the Word"

Hello. I think it would be very helpful to be able to suppress the "show solution" button with the "Speak the Word" content type. In other words, if I am making an educational game for my students, and I want them to learn a password from one part of the game, then speak the password in a different part of that game, it won't work if they can just "show solution" -- It would also work if I wanted them to look up the information in the appropriate source, and then try again when they know the answer. I think being able to suppress this button would really help to integrate this with other content types, because a lot of them already have that feature. 

Though usually my biggest sigh over h5p is the inability to change the colors of the buttons (I really, really, really want that feature, so badly) the ability to suppress the "show solution" is something I can imagine a lot of users would benefit from. These could be useful for quizzes in one-on-one tutoring, they could suddenly become part of all kinds of game creation projects, they could be used in escape rooms to great effect, and from a coding perspective, it offers a HUGE gains for only a few minutes' coding. 

Coupling that with the other requests, like the ability to have the "correct" and "incorrect" messages as audio files, would make this one of the best content types in an already stellar collection. Thanks.
