Encoder merge wav with video

Hi, have searched everywhere in forums but did not find what I was wondering about.
Has 200 audio files in wav and video files in h.264 each part so I want to merge both audio and video into the same file and have tried Encoder with stitch tools but it just became video, for example, audio after not at the same time.
Do not want to do in Premiere pro because it would take a lot of time to rename file names and export each file.
Is there a faster way?
