It can be done. You can record macros of your own inside powermill. If you tend to machine every job in the same way it can be really useful.
Say you always had a output workplace at the bottom centre of the part. You can macro that in then create arguments in the code to load in a block with the job and then rough etc. Can get really tricky but the powermill user forum on Autodesk is full of people that will help you with writing macros.
