Technically you could, but personally...
Allow me to explain.
Making multiple decks tends to slow down the program a bit, and there are actually some very good reasons why it’s good to mix everything together when you’re studying, like avoiding hints that make it easier than it should be.
You can make tags for your cards if you want to make all the past simple cards etc. easier to find later. Tags don’t change the order you study the cards in. I personally haven’t gotten much benefit out of tagging so I’ve stopped using that function.
