OK, here we go-

1) Go to the BARS window and click on the drums track to select it.
2) Open the NOTATION window.
3) Use the mouse to enter notes for the count-in.
4) On GM synths there is a stick click on note G2, or you can drag the note onto
the high hat, or anything else you prefer.
5) If you use minims in the first bar and crotchets in the second bar, you'll get a very professional - "one two, one two three four" !

If you've any problems entering notes using the mouse, get back to me.
Good luck.
