[request] individual Scan rate for multiple observe

Is there a way to change the scan rate for multiple observe ?
I know there is Settings.ObserveScanRate, however I think this is for all observe calls ?
e.g.
All 3 observes are all running and scanning in the background at the same time.
I need to check region1 for image1 every 60 seconds.
region2 for image2 every 30 seconds
and region3 for image3 the default scan rate which I think is 3 scans every second.

if not then I guess the next questions is how do I make my own thread in jython that wont interfere with sikuli
