Consolidate multiple lists, with auto-update

[Eric]

I have multiple lists that I'd like to consolidate, i.e., create a
consolidated list that contains all the entries in the first list followed by
all the entries in the second list..., etc.

Obviously I can simply cut and paste. But I wonder if there is any way to
do it automatically, so that the consolidated list will be automatically
updated as I edit and add/delete entries in the original lists.

Any suggestions?

Thanks.
