We didn't have a regular syntax we used throughout eCart, DataAssist, SecurityAssist, and other products that create forms.
You can highlight and inspect a current form to populate names from an existing form.
Since we had no standard really defined we decided to define one with Form Builder and we will start using the FormBuilder naming convention moving forward when we do updates to include form builder functionality in those tools.
To replace an existing form, highlight that form before entering form builder and those existing form element names will be used for the generated form.
