Welcome to the forum.

Do you have a Mac or PC version of BIAB? I don't know about Mac, but you can indeed do this to some extent on the PC version.

Go to Preferences, Count-in/Metronome. You will see a pull-down in which you can select a fill of a few different types.

Take a look at that, and then you may very well have a more specific request if you want some control that is missing.
