Assuming, as above said, that you do not mean the lead-in-bar, this would be my "solution": double the first measure (that is if you want to start with a C chord on measure 2, gice C in measure 1 and C in measure 2).
Go to "bar settings" on measure 1 (mouse right click) and set "all instruments" to mute.
Go to "bar settings" on measure 2 (mouse right click) and set "all instruments"
to "back to normal".
You may set this procedure for all choruses or restrict it to the first chorus.
Have fun!
