two source windows in ecb with default filters

[Micha Feigin]

Is it possible to define an ecb profile with two source windows each
with a different filter active by default ?

I want to make a source window for headers (.*\(H\|h\)) and a source
window for code (.*\(c\|cpp\|cc\|C)).

the ecb layout creator won't let me create two source windows, and I
couldn't see if its possible to set a default filter (it was forgotten
the next session).
