Unfortunately, I can do this only when retrieving data, in a VDEF,
not in a CDEF to be actually stored that way, right?

By the way, can I use VDEF in a export? from documentation it is
not evident when VDEF are allowed.

Finally, as this requirement comes frequently, will you eventually
consider to incorporate TOTAL (or SUM) CDEF a feature of RRDTools?

Thanks
