Drawing Table as a BOM of symbols

Hello everybody,

On an assembly drawing, I have a repeat region for the bill of material including balloons.

Then, I add some symbols for the manufacturing ("hexagone.sym").

I'd like to have a smart table which display the same number of row as the number of symbol "hexagone.sym". 

I add a look on the esupport but it was not helpful. I did not set any parameters as comp or connector in my symbol. 

If it's not possible, do you have an idea how to set a table with a message box asking for the number of row ? 

Best Regards,

Julien
