Limit sync to my selected tags or cards? How to manage the deck?

I have subsrcibed to the anking deck, but i was looking for a option to stay in sync with only few tags of the main deck. For instance, i want to keep all the cards tagged only with sketchy pharm. I move them into a new deck and delete the rest but how do I stop getting new other cards not related to sketchypharm, and stay in sync only with the subdeck or cards i have? help me with any workaround please.

I donโ€™t think thereโ€™s a way to do that yet.
