"4.4.1 Written Welding Procedure. All welds produced to the requirements of this specification shall
be accomplished in accordance with a written welding procedure. Guidelines for written welding
procedure contents for typical welding processes covered by this doccument are suggested in
AWS B2.1. The final decision on specific format and content shall be at the discretion of the
Engineering Authority."  <emphasis mine>

Also have a look at D17 Commentary C4.4 (you may find some relief here)

See B2.1 Section 2    (2.13 and followning Matrix)

B2.1 2000
2.1.3   "...The WPS may list variables recorded on the PQR within the full range permitted for
a qualification variable and practical limits determined by the employer for other than qualificaiton variables."

You diddn't think you could do this without buying more specifications did you  :)
