More than 1 fade track in matinee?

Hi, So I have a matinee but it’ll only let me use one fade track, I want to fade in with the colour black and fade out with the colour white, So I need to have two fade tracks, but it deselects/turns off the other fade track when I create another.

Is there any other way to have two fade effects work at the same time?

Thank you for any replies
