Is it possible to import multiple property via excel in 1C-Bitrix?

Question

1C-Bitrix

As I understand it, there are two ways, the first without using programming.

You need to create several lines of the same element (product) in excel / csv.

Those. if you have 3 values ​​​​in the field, then you need to add three lines that differ only in the value of this property.

And if the values ​​(photo) are more than 3 or 50? you can edit the code, and then it will be possible to specify the values ​​in one line in one column, separated by commas

Second, you need to change the code a little: For import to understand the multiple property of the file type, (values ​​are specified separated by commas) Insert into bitrix/modules/catalog/load_import/ csv_new_run.php

Dear programmers, can you please write the code needed for this case? I will be very grateful!

Here is my csv_new_run.php file:
