You can and could contact the CFM (unlikely to yield any useful info), but the process of converting entry classification requirements from no-prior service to prior service is not a simple process as it involves significant manpower funding changes that the CFM must justify and coordinate through HQ AF.
The suggestion of Air Force Recruiting Service (AFRS) is in the process of converting non prior service slots into prior service slots to accept more prior service trainees is extremely misleading.
AFRS has extremely limited, if any, influence or ability to meddle in converting manpower requirements by its own whims and choices. Be aware manpower requirements that AFRS gets to put new hire (no-prior service) and rehire (prior service) enlistment seekers into is coordinated and determined outside of the AFRS organization.
Any manpower requirements converting, if it happens, will not result in any significant numbers of increased quotas for prior service applicants.
The whole of the manpower that comprises the numbers of individuals needed to preform duties of the AFSC is constrained by authorized end strengths, established grade distribution and other guidelines as directed by Congress and the Department of the Air Force. This is why AFRS is awaiting word from the AF career field/functional manager who determines the justification and coordinates any such manpower requirement with HQ AF to get such changes approved.
Tied into complicating such manpower decisions is what is the impact (1) retrain opportunities for current active duty FTA and (2) on retention of already trained and qualified FTA seeking to get the needed CJR to reenlist and continue to be there to perform duties of the AFSC which includes increasingly more demanding performance of NCO duties. This oversimplified explanation connects to grade distribution and grade being connected to having the commensurate skill level and other additional qualifications and experience.

Manpower is not a program by itself which can be manipulated apart from the programs it supports.
