How to insert into a table field with value from a display method dependent of string

Question

as you might know, this is a nice way to dynamically set values to fields.

myTable.(fieldName2Id(myTable.TableId, fieldNameStr)) = "This value";
myTable.insert();

What I am wondering about is if there is any way to do it in a similar fashion with display methods, just dynamically get the values from them?

If i have the Display method name (i.e. itemName()) how can I do this...? something like this to demonstrate how i think:

methodNameStr = "ItemName";  
myTable.myField = mytable.(methodName2Id(myTable.TableId, methodNameStr));
myTable.insert();

Use DictTable.callObject(medhodName, buffer).

Common myTable;
DictTable dt;

//<SampleOnly>
str methodNameStr = "itemDescriptionOrName";
InventTable tmpTab;

select firstOnly tmpTab;
myTable = tmpTab;
//</SampleOnly>

dt = new DictTable(myTable.TableId);
dt.callObject(methodNameStr, myTable);

info(strFmt("%1", dt.callObject(methodNameStr, myTable)));
