Ok, then go to launchpad and file a wish list bug report and maybe the developers will program it that way but I doubt it.
The way it works is that grub will retain in the menu.lst or grub.conf file(hope I got that right) every kernel you have installed until you remove/purge a kernel and then run update-grub as sudo or root. Besides, there is no harm if you retain all the kernels released in a Ubuntu version at least if you partition is from 20-30 GB in size and they are good safety factors in case some kernel fails. What's so hard/unreasonable to learn how to do it the Ubuntu/Linux way. I believe most if not all Linux distro use grub and will have to be handled the same way. Somewhere in the past I think I ran across something that limited the number of kernels you could install(back in the grub1 days) and it would have worked as you suggest I think. Unless you are totally out of disk space it is not an issue. Just ignore it.
