what i do, is after i find the correct # of recruts on my BO to get mt guidelines rite. Say for example 10 for my BB4 , 28 for my BB5, & 55 for my BB6. I name my BO 10/28/55 saves me time in the long run if i wana play a smaller ship. But what you want would save the initial time of figureing it out, i recomend this
