AFAIK That's not possible using standard QMC configuration options, and I think for two reasons:
- Alert emails is an all-or-nothing-affair. Either you enable them, or you disable them globally.
- A shared Publisher hasn't the faintest idea were a QVW is coming from. Those are just anonymous document files to reload. It's only during the last step (Distribution) that the Publishier has to contact a QVS, and only if you distribute to a QVS.
Can't you duplicate your Publisher? That would eliminate today's risk of having a test reload job messing up the regular production reloads. There are Test Publisher licenses available as well.
