Yes, we've done the same thing here with the approval of ABS and no need to requalify.

Subject: [MW:2550] D1.1 - WPS - Semi-Auto vs Auto - Need new PQR/WPS
Hello,
Is a new PQR required if the process is changed from semi-automatic to
automatic? I am welding piles and would like to use a BUG-O system
with FCAW-GS and already have a PQR/WPS with FCAW-GS semi-automatic.
Can I use the existing PQR to create a new WPS as long as I stay
within the procedures?
Regards
