Logic 7.1.1: Ability to place downbeats? (Film Scoring Question)

Question

Here is my situation: I'm scoring a film and the director loves my music in this particular cue, and wants me to add a few more bars to the beginning of the cue as a lead in. My music currently starts on bar 5 at 109bpm in 4/4, however, in order to get it so sync up to picture, the first bar is running at 120bpm in 5/4 and bars 2-3 are running in 4/4 at 150bpm, with bar 4 used to set the cues 109bpm in 4/4 tempo. (I dont remember why I did this, but it works)
I obviously want to leave my music in sync with the picture, so I have locked all currently composed regions to SMPTE, however, when I change bars 2-4 to the proper 109bpm in 4/4 time in order to create more music in the beginning, the locked midi regions no longer start on downbeats (or any beat at all for that matter)
This exactly what should happen, as the regions are locked to SMPTE and are thus ignoring logics beat maps. However, I need to compose more music, and thus would like to have the cues function within logics beat maps once again. Is there a way to tell logic where the downbeats of bars should be, e.g. just drag and drop the barlines directly on a midi region? I believe digital performer has this ability (or it did back in 2002) and thus I was wondering if logic does as well.
Sorry if this is confusing. Any ideas on how to get the final result I'm looking for would be greatly appreciated. I thank you all in advance for any information at all.

Answer 1

Justin, thanks for referring to my method as a "method" LOL.
Yeah, it's a method I guess... here's how I did it.
First, I started with a new song and simply recreated Jonathan's tempo and time sigs as he described in his post, which made the tempo map look as follows:
1 1 1 1 Tempo 120.00 at 01:00:00:00    (5/4)
2 1 1 1 Tempo 150.00 at 01:00:02:15    (4/4)
3 1 1 1 Tempo 150.00 at 01:00:04:03
4 1 1 1 Tempo 109.00 at 01:00:05:21
5 1 1 1 Tempo 109.00 at 01:00:07:27
He said his count-in started at bar 4, first music at bar 5. So I made note of the timecode number for bars 4 and 5.
So I'm looking at this and thinking, "if bars 2 and 3 were at 109 bpm instead of 150, that would give him 2 extra bars in front of his count-in, making 3 good bars of 109."
OK, so I changed bars 2 & 3's tempo to 109! While I knew that this would change the SMPTE location for bars 4 and 5 (as well as 2 and 3), at least I was getting somewhere with the idea of establishing additional measures in front of his existing cue at the right tempo.
So the only question remaning was, "what tempo would bar 1 have to be changed to in order to make bar 4 (and 5) line up at their original SMPTE locations again? Using the mouse I adjusted the tempo at bar 1 until bar 4's SMPTE number was the same as it was before.
That's it! The map then became:
1 1 1 1 Tempo 234.00 at 01:00:00:00 (5/4)
2 1 1 1 Tempo 109.00 at 01:00:01:08 (4/4)
3 1 1 1 Tempo 109.00 at 01:00:03:15
4 1 1 1 Tempo 109.00 at 01:00:05:21
5 1 1 1 Tempo 109.00 at 01:00:07:27
