We need to have the ability to configure a field that points to another field that Jira current doesn't have the ability to do so.

Here is the layout:

Field A: lab1, lab2, lab3
Field B would be:

• lab1: eng1, eng2, eng3
• lab2: eng4, eng5, eng6
• lab3: eng7, eng8, eng9

Field B: is based on selection of Field A. If lab1 is selected then Field B would have eng1, eng2, eng3. If lab2 is selected, then Field B would have eng4, eng5, eng6. If lab3 is selected then Field B would have eng7, eng8, eng9.

We have seen this scenerio in the Project and Issue type relationship where the Issue type is based on the Project. We would like to have the same ability to create similar cascaded fields for the issue.
