Configure Interrupt Vector Table In e2Studio with smart configurator

I am facing issue while trying to configure the interrupt vector table. The status of interrupts for the added modules are not shown as "Used". 

The modules were imported as FIT components in the smart configurator. However, the interrupts for "Code Generator" components are  being shown as "Used". 

If the interrupt configuration of imported FIT components not supported in smart configurator, what is the method to configure the interrupt vector table in e2studio?
