coupon wheel prize

Hi, I want to make a wheel prize so i am making a coupon through your plugin.

i tick the option ‘Add received email to coupon’s allowed emails list’ so only the users which have given their emails will be able to use the coupon.
and also i set the option ‘Usage limit per user’ to 1

my question is if the user wins second time this coupon through the lucky wheel, will he be able to use it again?(i want this to happen)

Also i want to avoid the user to use the coupon many times without having earned the coupon second time. Beacause the coupon is sent through email i want to avoid the user to use the coupon code many times. Only if he earned it second time in lucky wheel i want the user to be able to use it again.

And a second question, can i make multiple unique coupons?

Thank you.
