FL Studio Tempo Help PLEASE!

I am using the Edit Events automation feature in FL Studio on the tempo.. but I can only use it on the tempo (coarse) not the tempo (fine).
So I can only jump a whole bpm at a time.
So if I have for example a song at 103.427 bpm.. I can only change it to 104.427 bpm, 110.427 bpm, 107.427 bpm etc.. I cannot change the numbers after the dot .
This is frustrating because Im using the edit events to move the audio clip as the song progresses so that the natural drums of the audio sample automatically re-adjusts to the second and fourth beat positions.
This way my own drums always hit in the right spot.. and the audio clip does its work moving left to right, right to left etc in order to make sure that the snare always hits on the 2nd and 4th beat of each pattern.
Anyone know how I can use the tempo fine on edit events?
Or any other control I can use to tell the program that I want the audio clip moved at certain parts to align itself at the 2nd and 4th beats?

Basically I wanna be able to move the tempo by like 6th steps or whatever instead of whole beats.. because I normally get the snares lined up quite good but they just need to be moved a bit either left or right.
