I have an assembly where I have a linear pattern of a part. I then need to create another linear pattern that starts mated to the last entity of the first linear pattern. This process can be repeated several times, with each new pattern seed starting mated to the last entity of the previous pattern.

Easy enough, but if at any point I change the number of items in a linear pattern, the next linear pattern in line is no longer mated to the last entity in the changed linear pattern, but rather the original last entity. Is there a way to always mate to the last entity in a linear pattern, regardless of the number of item in the linear pattern changing?
