Does anyone have experience in creating a Business Routing Rule using Exists function? ![](/sites/default/files/inline/images/images/Annotation%202019-04-02%20144221.png)
 
I've used the comma delimited 'In' function, but I would like more manageability. Entering and remove items from a look up table would be much easier to manage then changing the comma delimited string. Messages go to error state. ![](/sites/default/files/inline/images/images/Annotation%202019-04-02%20144732.png) Any help would be appreciated. This is my first post, so if I am doing anything wrong please let me know.
