Multiple Tabs Automatically Transfer To One Consolidated list

Hi,

Hope someone could help me please, I've attached a log of how i want it to look, but i cant figure it out how to do it.

Basically when a person completes a row on their tab id like the row copied over to 'Main Sheet' and if any amendments are made id like the data to change automatically on main sheet. Also id like the ability if possible to add/change the Person tabs to other names etc.

Any help would be amazing, thanks
