Are they 6 specific mobs in one location?
Are they the only mobs with that/those names?
If they are located in a smallish are that you can pull from one camp, and are using KissAssist, you can add their names to the MobsToPull list, adjust your pull radius to make sure al the mobs are in radius, and go to town.
If NOT all in a close area but not spread TOO much and have low chance of agro from other mobs you could also use KA with AdvPath, creating a path to each mob to be pulled.
MobsToPull listing (also has MobsToIgnore, MobsToBurn, and MezImmune) is found in your MQ2/Release/Macro folder in the kissassist_info.ini look for the zone in which you are hunting said mobs and add their name(s) to the pertinent line. Note: last time I used this list, it did ignore everything other than the mobs on the MobsToPull list, but that has been awhile, it may not, you may need to ad the name(s) of other mobs to the MobsToIgnore list if it wants to pull them.
If you are looking at pulling THIS Xnamed mob and THAT xnamed mob while ignoreing the 4 xnamed mobs just inbetween, you might be asking for more than a simple macro could do. Because I believe spawn id's can change even if the names do not, making that a bit unreliable
