Single process/thread that has multiple I/O patterns

I was wondering if fio can add support for doing workloads that has
finner granularity, for example, to simulate a single process/thread
that has multiple different I/O patterns.

It would be better if each I/O pattern can have it's own thinktime.

        rand_read_weight=1, 2-4ms
        seq_read_weight=5, 3ms
        seq_write_weight=5, 10ms

Thanks a lot.
