Copying Sales to Purchase order

We have company multiple companies X,Y

The company X creates a sales orders, then the  supply team creates purchase order from the same company by copying or manually typing the line and send it to the company Y by clicking send IC purchase order from Purchase order page which create  a sales order in company Y



The supply team manually type all the lines from ‘SO’ to ‘PO’ which includes comments!! I know we can use special order which will copy only lines with type = item but not comments

How can we also copy comments lines is there any way to make their life easier

We Use NAV 2016


 any suggestions would be appreciated


Thank you
