Remux Video, Audio, Subtitles and IG Menu in a m2ts file

[Olligator]

Hello community,
I have a m2ts file with a video track, 3 audio tracks, a subtitle track and even an IG menu is available. To demux this file is no problem. Only how or with what program I can remux the IG Menu in a m2ts container? Audio, video and subtitle track are no problem. This is possible with tsmuxer or eac3to. However, these programs ignore the IG Menu.
Can you help me?
Thx you.

Hi Olligator, IGFix 1.00 this simple program could do it, the problem is that it can no longer be purchased, it works IGS menu (multiplexed or non-multiplexed):

Thank you ocean for your answer.
The problem is unfortunately not solved.
The demo version of igfix does not work for the problem.
Does anyone have another idea?
