Currently, to create a record in the database, one needs a variable of type <Entity>. It could be a local variable, an aggregate function, or a form widget.
I frequently run into situations where I need to create one minor record in the database while I'm working with a bigger, much more significant record. Rather than waste a local variable and an Assign node for each of these trivial database entries, it would be nice to be able to just call a Create<EntityName> function and directly pass in the values I want to be stored in the database.
