(All new Adobe captivate) Mute Slide audio and plan a diff smartshape audio.

All New Adobe Captivate.

In a branching slide with 3 buttons. Is it possible to mute the slide audio on revisit? and after all the branching buttons are clicked is it possible to play a audio 'End of course' inserted in to a smartshape as well as show the object in which the End of course audio is inserted.

Thank you,
