Interpreters can now be filtered out of the selection process if they are banned from working with a specific LEP (patient or consumer depending on the title you use).  To create this condition, you need to open the interpreter's record in the the Interpreter Database and choose the Work Log tab.  On the bottom left you will find a type ahead field in which you can add the LEP's name.  Remember, this will only work if the LEP is in the Consumer database.  

As you can add an LEP to an interpreter's record, you can add an interpreter to an LEP's record.  When you create this entry in one, you create the corresponding info in the other.
