How to use genetic algorithm tool in optimization toolbox

I have a project I need to use Genetic Algorithm solver in Optimization Toolbox in MATLAB. So here is my problem. I have a chromosome which has two different sub-chromosome. In the first sub-chromosome, I have a bunch of order IDs some of the same, some of the different. In the second sub-chromosome, I have some number which shows the size of the batches of orders. So these sub-chromosomes have to be processed differently. I mean the first sub-chromosome have to be processed with different cross over and mutation operations and also the other sub-chromosome have to be processed with different cross over and mutation operations. Is there a chance to use this chromosome on Genetic Algorithm solver? If there is can you explain to me how to do this? If you can help me I'll be appreciated.
