Hooray! I was also hoping for the ability to change the timing that certain BL_ID's used, but this is good aswell!
for(%i = 0; %i < ClientGroup.getCount(); %i++) { %obj = ClientGroup.getObject(%i); commandToClient(%obj, 'MessageBoxOK', %header, %text); }
commandToAll('MessageBoxOK', %header, %text);
