Writeback Table - Limiting number of rows

I use  the writeback table to add forecast data inputted by myself. Now i have a rank and sorted to it. But now if I bulk edit all of the almost 7000 rows are selected and bulk edited. I would like to get an option in the writeback table to limit the number of rows. Is this already possible and have i missed a limit function or is it not in the extension (yet).

Thanks in advance for the help.
