How can customers choose which voucher to use?

[Alexgaw]

Hi,

 

 

I have an issue with the cart rules.

 

I have a cart rule of 10% that is highlighted (auto added to the cart) and cannot be combined with any other offers.

 

I also have voucher codes sent by email to customers.

 

If a customer want to use the voucher code instead of the auto-voucher that is already in the cart  he is not able to remove/replace/select what voucher to use.

 

Is this a bug, or is there a work around. Note, I do want to keep the set up as it is but want to give the customers the ability to cancel existing cart rule highlighted in the cart and enter another voucher code.

 

HOW CAN THIS BE DONE?

 

/Thanks
