How to set up the order of uploading images from 1C to CommerceML?

Question

1C

Hello!
I set up uploading from 1C to the site through the standard CommerceML protocol. The site is not on Bitrix, 1C 8.3 + Management of a small company.
Most of the goods have several pictures, part with a description. In 1Ske they are arranged alphabetically (image file name + description (if specified)). But when unloading, they go in some incomprehensible order.
I thought from the side of the site to sort the array of photos alphabetically - but it won’t work, because if the photo does not have a description, 1Ska puts the file name instead. Those. some will be "description" and some "file name".
Actually, the questions are:
1. How can I set up the order of uploading photos in 1C?
2. Is it possible to turn off the display of a photo description in 1C if the description is not set directly?
UPD: 3. What are the default photos based on? By upload date or what?
UPD2: I figured out question 3 - the photos are arranged in alphabetical order by file name in the 1c database ( like 02020abee85a11e2afc3902b3442b8e8_0c993b4d418011e592aa8ce4607c686a.jpg )
