Redo completed tasks

Hi People and @mmumshad @KodeKloud @Inderpreet

I’m really glad to be part of kodekloud community and very delighted that joined here to practice with different challenging tasks. I have a suggestion that may be interesting to beginners like me.

I wish I could redo those tasks optionally which have been completed successfully to become master in that specific. I wish I could play more with Iptables rich rules periodically.

I hope you have the same sensation, that you need more practice.
