Just save the game when the characters are about to level up. If you are not satisfied with the level up, load the saved game, and pass the turn (do not let your characters level up that turn because the level up stats will be the same). Then level up. If you are not satisfied with that either, repeat the same process (load before your levelled up, pass a turn, level up and see if you are satisfied with the increases).

Note that at low levels (below 50) stats are capped. So you cannot gain some stats no matter what. Otherwise, the random number generator is such that you can either gain absolutely nothing (for example, 1 hp from a level up), or gain a high amount of increases (all stats increase). Its very random, so you should take your chances till you get something decent.
