how to set timing exceptions on specific clock domains

[woshicloud]

for example, when I setting multi-cycle path -from DFF0 -to DFF1;
but DFF0 has two clock source CLK0A and CLK0B and DFF1 has two clock source CLK1A and CLK1B.
I just want to set CLK0A-DFF0 to CLK1B-DFF1 as multi-cycle and do not want to set timing exception on other cases.
How can I write the exception?
please help!

I don't have access to the manual , but does it have -through option ?
-from [get_clocks CLK1] -through [get_pins DFF0/Q] -through [get_pins DFF1/D] -to [get_clocks CLK2]
