"one-upsmanship" -HAHA Hee hee.
If you have a lot of data. the Option-Drag can still be cumbersome, so
you may want to try this variation:
In the example you gave, Click to place your insertion point between
the 4 & 5 on the first row.
Don't drag, but just scroll as necessary to view the last row of data.
Position your pointer at the end of the data (after the last 8 in your
sample) & hold down Shift+Option+Command while you click there.
