concatenating strings like summing numbers

I'd like to join string within a group, preferable with a separator, the same
way I'd sum values.
So, I'd like to write somethign like
=Join( Fields!Email.Value, ";" )
to obtain a string of semicolon separated substrings, the same way I'd say
=Sum( Fields!Number.Value) to get the sum of numeric field.
Does anyone know a way to do this?Having exactly the same problem. Thought of writing custom code, but not sure
what arguments to pass. The code had an array of strings as an argument, but
when i called the function the same way I would call an aggregate, got an
error message saying that aggregates can take only numeric values as
arguments..
