I have probably a simple question but am unclear on the lingo.  We don't have all that many Cloud users as the automation, lookups, dynamic fields, and other limitations.  

The documentation says that Lookup Tables are meant as a replacement of Entities.  I don't seem to find the ability to update the lookup table using workflow.  The simple scenario is to have a Form hooked up to a lookup table, change a field, and then have workflow update that lookup table.  Is that possible?  I don't seem to be putting the pieces together on the interaction between the items.

Thanks,

Chris
