You can use the % wildcard to get a set of paths to match. For example if you have these paths:
Refrigerator1/Unit1/hoa
Refrigerator1/Unit1/temp
Refrigerator1/Unit2/hoa
Refrigerator1/Unit2/temp
Refrigerator2/Unit1/hoa
Refrigerator2/Unit1/temp
Refrigerator2/Unit2/hoa
Refrigerator2/Unit2/temp
‘Refrigerator1%’ (without quotes) gives you:
Refrigerator1/Unit1/hoa
Refrigerator1/Unit1/temp
Refrigerator1/Unit2/hoa
Refrigerator1/Unit2/temp
‘%Unit1%’ (without quotes) gives you:
Refrigerator1/Unit1/hoa
Refrigerator1/Unit1/temp
Refrigerator2/Unit1/hoa
Refrigerator2/Unit1/temp
