Layering sequences

hi,

i am using layering sequences in my testbench. need to pass the transactions from higher sequence to lower sequence and then to DUT through driver. and need to collect the response from the DUT and send back this response , till higher sequence.
and then need to perform some computations in higher sequence.

please let me know if it is possible to implement in the way above mentioned.

There is a Cookbook section on layering sequences here.
