Can I control anchored frame below distance to text?

[Studio Smalbro]

Hi
I am running FrameMaker 11 (Which I am growing to like btw). I am 
inserting some anchored frames in my text with the option "below current 
line". Is there a way to control how far below the current line the 
anchored frame is inserted? I have tried using object styles, but with 
little luck. Can I hack it in ini settings eventually?

regards
Bjørn
