Yes, even you can stake the rest of the amount you make can be a stake in the same validator, even I am doing the same thing because it will definitely help increase your holding as long as possible.
Thanks for reminding me of this! I will definitely stake again my rewards when I reach my target figure, and hopefully could do it by next week.
