If Currecy ISO code is pulled in to a bionice rule, we are not allowing customer to use this in a merge. The field is not present, and after this we go to global currency. We would like to see the option to be able to pull this field into the merge of the rule. This seems to become an issue when we are trying to use this in the action. We would like to see the same ability that can be used in a single fetch, which will allow you to use the Currency ISO Code.
