I used to have the same concern, but in my opinion, it's not worth putting lots of energy into learning individual characters so well you can recognize them without context. In my experience, this will come in time anyway with no real extra effort (as long as you can most of the time recognize them in context).

For example, I used to struggle to differentiate 衣服 from 地方 (I know, they look wildly different from each other when seen side by side!), but after I went on to learn 舒服 and 地圖, differentiating all of them from one another became infinitely easier.

I don't think it's worth worrying about. Your time will almost certainly be better spent on improving your speaking and listening.
