Quantization

Hi, I'm trying out Composer, and I like what I've seen. I've been looking in menus, but haven't seen anything to address quantization. I'm importing my midi compositions from Cakewalk Sonar and a hardware sequencer, and invariably, no two programs are ever going to line up completely.
When I originally wrote the songs on the Kawai sequencer I had to physically offset the note data, because there was no "chase" operation. Plus a few were never quantized to begin with, so in Sonar's staff view, what are beautifully seq'd and looped patterns, show up as a long , snake-like string of notes.
A few things I'd like to see: 1)define the position of a note with the "note choice" function (i.e.: line up an eigth by choosing "eigth" and clicking the note to be affected). 2) Overall quantization for a motif, chord, passage, etc... where if I select a group of notes that is not quite lined up, I can drag them to the nearest appropriate starting point. 3)account for offset ---- When I repositioned a track in Sonar to align the notes with the beginning of a measure and then set an offset to actually play the notes where they originally sound, saved it to midi, and imported it into Composer to print it out, the notes were lined up exactly where they were before I had made the changes.
The last is not something I really expect to see corrected or even addressed, as every sequencer and notation program has its own way of accounting for issues like this.
Now that I think about, I've been working inside sequencers so long, that I've almost forgotten what it's like to write pickups and repeat symbols. Well I guess I answered at least one of my own questions.
BTW, Composer is a quite beautiful-looking program and I love the fact that it addresses grace notes quite nicely. That alone might sell me completely on this program. Now all I need to do is convince my wife that we really need it.
Thanks,
