FX functionality added to the Vizlib Writeback Table's property "Column Name (export)"

Hi, I have a case where we need to have a Writeback for data by month over 18 months and now in March 2023 it shall be like 2023-03, 2023-04, etc. And in April the columns shall change to 2023-04, 2023-05, etc.

My plan was to have the column names, also for EXPORT, as variables from Qlik Sense. Problem is that the Vizlib Writeback Table's property "Column Name (export)" is only handled as a string. 

So my suggestion is that the "Column Name (Export)" shall be possible to set with variable by giving it FX functionallity.

Thanks!
