Is there a method to exclude a specific field from the sync process? I assume that EasySync always excludes calc and summaries and probably globals (does it exclude globals?) and only lets through numbers, text, dates, times and containers etc. If there are some trigger fields on the mobile solution that have no bearing on the hosted files is there a way to tell the syncing process to ignore a field so that you don't have to add that structure on the host file?

Thanks.

Yes. This is clearly documented on the website.
