1- Define a user macro to map names
   { "ReceivedName" : "VisibleName", "ReceivedName1" : "VisibleName1", ...}
2- Trapper item receives data (Master item)
        2.1 { "ReceivedName" : "value", "ReceivedName1" : "value" ... }
3- Dependent from Master (intermediate)
        3.1 Preprocess with the macro constructing the LLD input
        [ {"

":"VisibleName1" ...}
           ...
        ]
4- LLD dependent from intermediate
        4.1 Item prototype with the name in "{#NAME}"
5- Change something in the macro
   { "ReceivedName" : "OtherName", "ReceivedName1" : "OtherName1" ...}
        5.1 - No changes in Items created by the LLD
6- Update the description of the intermediate item (any non "fundamental" field)
        6.1- Starts working as expected
