Hi ,  
can there be an option to make sub process multi instance as a batch of lets say some instances.  
For example : multi instance collection list contains 50 items , i want make batch of 10 instance . so one batch contains 10 parallel instances and like wise there might be 5 batch of 10 parallel instances each.

You could partition the desired chunks (i.e. in a script task) before the sub process and then loop in serial over the chunks and loop parallel for the instances within the chunk.
