How to archive all done tasks?

[nhvu1988]

Hi @huytd, thank for your awesome app, I love to use it daily and there're a lot of done tasks everyday. But I would like to keep them for a week to get the overview of what have been done in the whole week and will archive all of them at the end of Sunday or in the morning of Monday. Do we have any single command that help to do this? Thank you!
