Go to Admin>Options>Misc and there under Handbook Assignment you will find the place to personalize your club's default Bible version to NIV.
Now, if you want to change one clubber to NKJV of KJV
(if you allow clubbers to opt out of the standard version you use in your club,) then you open the clubber record, go to the Misc tab and you'll see the place to customize just one clubber's Bible Translation.
