Excel Writer with dynamic Sheet Name

HI I am using v5.9.2.3 and trying to create an excel file with dynamically named sheets using a variable i set before in a loop , called <SheetName>

instead of say 50 sheets of data, i get 1 sheet named <SheetName>. Does ETL excel writer support variables in the writer config as shown below

if not, can you provide/support this feature or tell me how to arrange this. I have the requirement to generate a report of about 100 sheets. Each sheet name is a number that means something.

Looking at it now

Here is an example of how it can be done based on the example in the default repository

Thanks , it works, i was close, seems that i needed the {GetVariable('<MySheetName>')} syntax for sheet name:

i am not sure what SourceChanged; in the calculation does however.
