I need a help in using crash utility.

I have a structure like this

struct a {
    ...
    struct task_struct task;
    ...
    struct list_head list;
    ...
}

It is possible to get the address of the task structure using -s a.task option in the list command. But what if i want to get the value of a member inside task, say task.comm? Is it possible to make the list command to print to it directly?
