[rules-users] [Drools Activation-group] / how to set many activation groups

Hello, I am trying to implement some rules that need more that a unique Activation-group. My case is related to some Voucher codes for online shopping. A simple case works great, by defining an Activation-group to make sure 2 Voucher codes cannot be used at the same time. But now I need 2 Voucher codes (say Code 1, Code 2) to be compatible (no activation-group) and a 3rd code (Code 3) to be disabled if Code 1 or Code 2 is used. If I use a XOR group name as an Activation-group, then Code 1 and Code 2 will have a same Activation-group and will be exclusive (which I do not want). Do you know a way of setting multiple Activation-Groups for example, or any workaround for that case ?
