PO Comment Box - Is there a thing?

SUGGESTED

I'm tasked with organizing my purchasing department.

Right now they are putting comments such as:

"confirm to email xxx@ourcompanydomain . com " 

or 

"ready in september"

random notes as line items under the items purchased.

I'm not sure that is the best practice at keeping the data clean.

I tried to edit the template of the PO but I can't find any way to add a "comment" section that they could fill out when creating a PO to send to a vendor.

Any ideas?
