Virtual Hosts question

I'm still learning how to configure exim....

I have two questions about virtual hosts:

1) Is there anyway to lump all the aliases in a single file in the form:

user@???:    real@???
user@???:    real2@???

as opposed to having the aliases in a per-domain file?

2) Is there anyway to have unmatched local_part @ virtual domains sent to
some default user? Ideally I'd like to add a line similar to the
following to the above wished-for file:

domain.dom:    real@???

or

@domain.dom:    real@???

or even

*@domain.dom:    real@???

Thanks in advance:)
