Ghseet - Row Limitation

The one issue I have faced is row limitation in the G-Sheet, which is capped at 20,000 rows. Would be helpful if we could expand the capping or if we could add a feature like getting data of a particular group/chat, which will give it a longer runway before it reaches the cap

And if we could also delete the old data from the g-sheet (like deleting data which is more than a month old), this will inturn free up rows.
