Always sending apps to managed space

Hi!
Is it possible to always send windows to managed space even if they hav 
a specified size? Apart from GIMP this would be nice and for GIMP there 
would be a "send to ~" specified in wmiirc anyway.
For example Brasero uses a small burn dialog (when burning iso files) 
which is sent to floating space. I can manually send it to managed space 
but I would like that to happen automatically since there is no problem 
with it.
