Question on multiple corpses

[Baron]

Question #1... is there a command that tells you how many corpses you have in a zone. For example if you needed to find and rez multiple corpses other than finding and rezzing them one at a time and checking to see if you have any corpses left in the zone by hitting /corpse; is there a command that gives you a total number of corpses left.

Question #2... if you have multiple corpses in a zone and a necro summons 1, is there any way to insure that when they cast summon again that they don't just summon the same one over and over. How does the spell determine which one to summon? Closest? Most recent? Oldest? Etc.... Again, other than the obvious way of summoning, then rezzing, then summoning again.
