Need "comment to supplier"

The comments field is useful for our own internal project management info.

When producing POs, it is helpful to be able to make a comment that will be seen by the supplier.

These things are not that same, and the info should not be mixed, because sometimes we have confidential info in "comment" that should not be sent to the supplier.

So it would be useful to have a second field, "Comment to Supplier", next to the existing "Comment" field.
