Actually I can see why you may request such feature based on how delta for zerobot mutation works. But trust me that with your idea it will be even worse. All the zerobots will end up evolving and dying without a chance for natural selection to kick in.
The zerobot algorithm was developed and refined for about only 1 year and I stopped work on it as soon as I got a result. I did not try it again after that. So I have no 100% proof that it even works consistently. I am going to revisit this soon.
The most time consuming algorithm is the survival evolution. When I first developed it, it was more effective than normal evolution. Now I am not sure if it still is mainly because of how much the program changed. However it still has clear advantages other than speed of evolution therefore in the long run my algo should be better. I am publishing this thing as a general algorithm to be used not only in db, so when it is prove of concept time, it should just work. Unfortunately prove of concept may take longer than earning my AA. One thing my algorithm did not change is how slow evolution is.
