Warm-up Puzzles

Hello everyone.
I have this very strange idea.
I think there should be a type of puzzles that are ridiculously easy, they shouldnt count for rating or anything, i dont think they should even be permanent (saved like normal puzles).
But very easy things, like a (regular) mate in one or two.
very easy noticable forks. very easly abusable pins (attack a pinned piece with a pawn and stuff)
"And why would this be?" you might ask.
Well its basically to "warm up" some very easy tactics, just before a game, you get the point.
They shouldnt be intense but be quick, maybe even with a build in timer or something, and a counter to see how much you did.
It could have an option, do (choose a number) amount of puzzles, and it times how long it takes you.
They should not at all replace real puzzles (currently under puzzles).
they are more as an extra as I said, to warm up.
Ive heard a couple of IM's warming up this way (but on paper, not digitally) and I think it might be a neat feature.

lichess.org/practice is a bit like that.

@lovlas im searching more in the terms of 100's of puzzles in quick succesion.
if what i proposed is not possible, maybe a mode with an option to pick what rating you want your puzzles to be.
As i said, i dont do this for my rating or anything like that so if they dont get counted i dont really care.

There are a few great books that has this if you are interested. The Polgar one is great.

@lovlas so i heard, i just bought 100 euros on chess books tho, and im a poor boy xd.
+ i know, but a site like this has so much options, so much more unique combinations.
+ Polgar starts easy, but ive seen the book and it goesw into some pretty advanced puzzles, which is nice, but not what i am searching right now, finding advanced more difficult chess tactics is easier then finding easy ones.
Thanks for the advice tho.

*After some time of thinking mate in 2 seems like a more logical option (instead of one).
but i more or less mean, bulk excercises of the elo leven you decide yourself, instead of a fixed elo.
