Is there a way to put a specific amount of Kanji characters on a site / program to cram? I suppose Anki can do this but since the update I have not been messing with it too much.

What I want is to somehow re-study the “freshest” kanji that I have learned (Like, the last 20 kanji that I have learned up so far) Sort of like a way to remember them better.

The only way I can think of is to tag the newest kanji with a specific tag and then cram said tag. Any other ideas?

Thanks
