Philippe,

This, along with all your other queries on this forum, are constantly gearing me towards giving the same answer that you previously had: What you require cannot be given neither by this forum nor our technical support team. You require much more than what most of our users need on an everyday basis and some very specific features that aren't available.

I'm going to have to suggest again that you contact your reseller in order to get a quote for a custom modification of the system. You can put all your eggs in one basket of course and have everything done as a single job.

Or, we could put this as a series of feature requests, but before any of them are implemented you'll have to be patient - it could be months or even years before it's done this way.
