How to import from xml.zip link?

Question

WordPress

Hello!
There is a paid Wordpress template, support for which, for known reasons, is currently unavailable - that's putting it mildly.
The import wp pro plugin is built into this template (I also wrote to their support, there is no answer yet and .. all the same, I don’t know if it will be).
So, you need to import goods that are constantly updated using a link like https: // something there.xml.zip
"Something there" can only be given in zip and nothing else.
Import wp pro, in turn, can only process a link to a file without a zip.
It is not possible to manually update each file (link), because there are several hundred of them, and updating is necessary every day!
Powerful WP All Import (or similar) cannot be used, as this paid template has a number of vital add-ons that are made only for import wp pro.
How can I feed import wp pro links, but without the archive?
Hook, link modification, cloud solution, feature... maybe something else. Not strong in programming, but unzip_file works by default in Wordpress, but this plugin implements it this way.
Thanks in advance!
