How to add instructions & increase field width for a step name in Business Process flow

Hi There,

I am wondering how could we add instructions for each step name in a business process flow. 

Currently we have 4 stages with 10 step names. I would like to add brief instruction beside each step name to instruct the user on what to fill in?  Could this be done?

Secondly, is it possible to increase the field width for a step name within a BPF stage? 

Please advise.

Thanks,
