Enhancement request - code assistant for common table expression alias

[zitot]

e.g.
with tbl1 as (select stvterm_code from stvterm),
tbl2 as (select T.stv.. from tbl1 T)

or
with tbl1 as (select stvterm_code from stvterm)
select T.stv.. from tbl1 T

It would be nice if autocomplete could work on T. here when I press F6.
