create valuset dependent on 2 segments

Hello,

Question. I am creating parameters for a concurrent program. I have created valuesets Project Name, Project Number and Task Number. I would like the Task number to be disabled and dependent on if a value is given for Project Name or Project Number. Is there a way to make it dependent on two value sets? Right now when I test, Task Number is only depended on Project Number and is disabled until a value given.

I am trying to make the Task valueset dependent on either Projects Name or Project Number , can this be done?

WHERE (PROJECT_ID = :$FLEX$.XXPA_PROJECTS_NAME OR PROJECT_ID = :$FLEX$.XXPA_PROJECT_NUMBER)
