How to generate announcements on elements?

Question

1C-Bitrix

Proger 1c set up the import in such a way that on the site for all products the "announcement" is pulled from the "name for the site" property of the nomenclature.
He can’t remove it, because from his words:

There is no concept of an announcement in 1s and why announcements on the site are formed from the property "name for the site" is a mystery ..

1) How can we make sure that the property "product description" is substituted in the announcement, instead of "name for the site"
2) How can we make sure that the announcement of the elements is not affected at all when synchronizing 1c and the site? It turns out that we cannot even write them down manually, because they are overwritten.

Change the programmer, and your student will fool you.
