Obc configuration

Hello all,
I have a question about OBC special configuration in CROCO, 2 questions really.

Is it possible to configure the model to have different open boundary conditions in different boarders , e.g. orlanski at east and charact at north ?

Is it possible to have tides in just only one boarder ? e.g. Tides activated in north and non activated in east ?
Please, can anyone gave an example of how configure cppdef.h in any of these cases , if is it possible.
Thanks in advance,
Marcio.
