How to merge videos and add audio in a single command using ffmpeg?

I use the following commands to concat audio-less video files to one and add audio to it,

To concat individual videos,

ffmpeg -i 1.mp4 -i 2.mp4 -i 3.mp4 -i 4.mp4 -i 5.mp4 -filter_complex 'concat=n=5:v=1:a=0[out]' -map '[out]' -strict -2 -y video_withoutaudio.mp4

To add audio,

ffmpeg -i video_withoutaudio.mp4 -i audio.mp4 -c:v copy -c:a aac -strict -2 video_withaudio.mp4

is there a way to combine these two commands to one?

My requirement is to optimise the commands as I have 1000+ commands taking a lot of time to complete, hoping combining these two to one will save some time.

Thanks in advance!

Use

ffmpeg  -i 1.mp4 -i 2.mp4 -i 3.mp4 -i 4.mp4 -i 5.mp4 -i audio.mp4 
        -filter_complex 'concat=n=5:v=1:a=0[out]'
        -map '[out]' -map a -c:a aac -strict -2 -y video_withaudio.mp4

I assume that none of the concat videos have audio. If they do, the result will be unexpected.
