[Tex/LaTex] The text instead of chapter number

page-numberingprogrammingtable of contents

I just get some code from Pretty Table of Contents and modify it for my purpose)).
But I need some variable text parameter or command for using instead of chapter number in the Table of Contents.
Something like new command for example:

\MyChapter{683(19)-021-15-T1}{The modernization of energetic system of someplace}

and this must create new chapter with number of "683(19)-021-15-T1" and name
"The modernization of energetic system of someplace" like

683(19)-021-15-T1

The modernisation of energetic system of someplace…………….15

or so.

Can you explain how can I do it?

There is "my" working code and a screenshot of created pdf file, but to my shame, I'm not too versed in the code of latex and didn't succeed in solving this problem((.

You have chosen a very sophisticated design, which does not help clarify what exactly you are aiming at.

Here is an approach. Look at the parts of the code near %%%%%% //////////// CHANGES FOR QUESTION. Look also at the way \chapter is input in the main text.

It would be simpler to explain were it not for the humongous macros before. I had to keep most of the preamble which is too complex to think about modifying at my age, but I killed most of the document body.
