There seems to be no way of creating a fementation profile that might include for example a diacetyl rest for lagers etc. The only fields available are Primary, Secondary, Tertiary and Age for. In most cases Lager profiles would include primary, diacetyl rest, secondary (lagering) and Age for. For me 'Age for' mostly represents carbonation and aging either by bottle or keg and Secondary in this case would represent the lagering process. Maybe being able to add custom labels to these fields and being able to save would be a good start.
