After sorted by one of sample annotations, is main plot sorted by mutation by that annotation

[wangzunq]

Describe the issue
So I want the oncoplot cluster by cohort, which has A, B,C and is one of sample annotations. Also, I want to still keep gene sorted by mutation frequency as well as sample sorted by mutation frequency in each cohort as well. So it looks like a waterfall for each cohort.
The question is: when I choose sortbyAnnotation(cohort) will the order per cohort is sorted by sample level mutation frequency(meaning the samples in each cohort is sorted independently according to mutation frequency)
Thank you for clarifying.
