CODECOMPOSER: GUI Composer: Is it possible to link GUI value to a value via pointer

Tool/software:

I want to do something like on target

typedef struct{

bool enable

} TEST_STRUCT;

TEST_STRUCT array[10]

TEST_STRUCT *array_ptr = &array[3]

On GUI

link a checkbox, for example, to array_ptr->enable.  

Is it possible?

On my first attempt to do so, I get an error:

Thanks!
