Transposing One Track

I already created an SI-Bass track and have data there for all but last few measures of song, key of A.  But, I need the tune a half step lower for vocal range, so....
 
Transpose from the Inspector is only working on that single track right, not the project, and it's non-destructive so I can finish the bass line and transpose (-1 on the slider)?  When I record live guitars I'll just tune them down to Ab and then record the vocal over all of that.
 
That shouldn't be a problem right?  X2 won't have a conflict during export or anything?  Thanks.

That Inpsector thing works just fine.  For the record, I actually highlight the track and use the Process | Transpose command because the Inspector offset can be confusing.  By that I mean that the display in Staff is sometimes weird and everything you play will be transposed as you are playing--which is fine if you keep that in mind.  I just like to transpose the MIDI notes and let a C be a C on the keyboard.
