That would be very nice! Especially adding the ability to use the setting
from a real compiler would be very helpful.

Wave supports serializing all internal settings using Boost.Serialization,
if enabled (wave::context is serializable). That stores all macros, seen
headers with #pragma once, etc. which essentially allows to restore a
previous session.
