Project instructions not visible to vendors?

When adding a project, there are 2 fields for inserting notes - Customer notes and Internal notes. I filled out both of these, however in the vendor portal neither of these fields are shown. I was wondering if there is any way where I can add instructions which are shown to the vendor in a similar field instead of attaching a file with instructions. At the moment, in the vendor portal, there appears the following message in the Instructions section 'There are no specific instructions for this job'.
