no steinberg didnt miss a trick

fruity loops is basically a midi trigger .. (at least version 1 i used in 1998 - you had no direct control over the waveform, you just activated the little pattern knobs - that was it ^^)
so you have to do it with groove agent one - which can drag and drop btw. and has several outputs and some stuff like pitch and filter and even a rudimentary waveeditor. groove agent alone is superiour to that old fruityloops "sequenzer" ^^
just do that!
just drag and drop waves from media bay (F5) to the pads - then record a simple line or draw them in the key editor (piano roll) - voila..
if you paste a second hihat etc on another note you can just drag all the notes in the midi part to the new note - or you could trigger both a alterntive. etc.. its the way to do it.
