Wishlist: Spray objects - limited area

As it is today, If I want to limit the sprayed objects into a area limited by a closed path, I have to spray first, and then use "Set clip".

Here's a spray method I wish for:

Make one or more small objects that shall be used as spray source.
Then draw a closed path that cover an area that is suitable to contain several small objects.
Place the closed path under (lower in z order) the spray source and select spray tool.
There should be a check button labeled "limited area defined" or something similar.

Now: when spraying, only the area inside the closed path will fill up with spray clones (or whatever you call those small objects created by spray tool).
Also, the sprayed objects shouldn't be clipped (like set clip function does), but only objects that fits as whole objects are placet within the closed path.

A simple drawing is included to depict an example on how I thinking of the result of such a function.

Thanks
