How can I remove the first 30 second of 40 min video and add watermark also doing bulk using ffmpeg?

Question

I was able to add watermark to multiple video using

for %%a in ("*.ts") do ffmpeg -i "%%a" -i  logoCopy.png -filter_complex "overlay=main_w-overlay_w-40:40" "Logo\%%~na.mp4"

And now I'm trying to cut the first 30 second of the video and add watermark at the same time, I was able to cut the first 3o seconds using:

ffmpeg -i input.ts -ss 00:00:20 -map 0 -codec copy output.ts

Any one can help me combine the seouncd command to the first one?
