Search for specific meteor size

I spend tons on plutonium to find the right meteor. I make a ton, so no issue, but constantly refreshing them to find the right size is tedious. At a certain point we only get 80+ in diameter, rarely in the 49-60 range, which will mess up its surroundings. Since we have the tech to search for them and bring them down, how about an option to spend more probes, perhaps 2 to 3 times as many for a specific diameter range?

At least I would like to see a disregard/delete option, so "stupid" meteors do not fill up all slots.
