Some farms have multiple hospital pens and dry pens, either because of multiple locations or severity of the sickness (hospital stalls vs pack).  I could see benefit for the dairies, if they have multiple pens assigned as dry or hospital, the entry screen would pop up with just the pens that are assigned as dry or hospital.  Example- hospitals are 10 and 30.  When entering a polyflex treatment, have pens 10 and 30 pop up and the user selects which one she is going to.  This would save having to use protocols and multiple places to change.  The pens that pop up are the ones setup in the farm setup screen.
