Help with a repeat, please

Hello
I have a song with 3 verses (plus a chorus each time), and at the end, I want to let the chorus play one more time. In other words, verse 1, chorus, verse 2, chorus, verse 3, chorus, chorus. Currently, my sheet music contains verse (bar 1 to 40), followed by chorus (bar 41 to 61) , so I can just repeat the entire thing three times, but then I want to play the chorus (bar 41 to 61) one more time.
Can anyone explain to me how to do that?
Thanks
Samuel
