fetching data from bloomberg

You can create the group, that's certainly one way to go. Group creation accepts wildcards, so if the series have a naming pattern, you could use a wildcard.

Or you could use the @wlookup function to return the names of the series in your workfile (again matching a pattern if you wanted).

But, if you're fetching all the series in the same program, you must already have the names of the 100 series in the program some how to begin with.
