I took a look at the pinger a couple of months ago for the 4.3 branch to
figure out what the mechanism was and AFAIK your question is not
possible. Depending on number of pinger threads and interval the
endpoints get assigned a random value and something like 
currenttimeinseconds%maxvalue determins which endpoints are pinged. You
might want to influence this random number (partition IIRC). But this
depends on you db_mode (I guess it will not work when caching is active
in kamailio)

But you can do this yourself from an external process (like sipsak) if
you wish (and have the location records in a database).
