Create mkv files on batch

[JU4NiT0]

Hello everyone,
I'm looking for help with batch automations to create MKV files.
To start with, I've figured out how to convert MP4 to MKV using the following code:

FOR /R %%A IN (*.mp4) DO "***********\MKVToolNix\mkvmerge.exe" -o "%%~dpnA.mkv" "%%~dpnxA"

Next, I'd like to integrate external subtitles into these MKV files, with classified and named tracks. For this I use the batch method by creating a .json option file of the first file with MKVToolnix.
Unfortunately, either the video and subtitles are duplicated, or the subtitle tracks are not embedded, as the lines between "(" and ")" must be removed. This is a pity, as this method works perfectly well when you have different subtitles for the same episode, as they are automatically detected for each one.
Is there a technique for doing this correctly?

Then in the final phase, I'd like to change the name of these files so that I can sort them in my library.
For example, I have :
Special Ops Lioness 01x01 Sacrificial Soldiers.mkv
Special Ops Lioness 01x02 The Beating.mkv
Special Ops Lioness 01x03 Bruise Like a Fist.mkv

And I'd like to get something like :
Special.Ops.Lioness.S01E01.1080p.mkv
Special.Ops.Lioness.S01E02.1080p.mkv
Special.Ops.Lioness.S01E03.1080p.mkv

Once again, what would be a simple way of achieving this?
The best thing would be to have everything in a single batch!

Try this code. Manipulate as required

set title=Special Ops Lioness 01x02 The Beating.mkv
set pt1=%title:~0,19%
set pt2=%title:~20,2%
set pt3=%title:~23,2%
set title1=%pt1%.S%pt2%E%pt3%.1080p.mkv
set title1=%title1: =.%
echo %title1%

Input : Special Ops Lioness 01x02 The Beating.mkv
Output : Special.Ops.Lioness.S01E02.1080p.mkv
