Consultation on integration with OpenCart

There is an action Import products from Opencart 1. It has the ability to load Options and Attributes into filters in OneBox [file]5538[/file] Is it possible to refine the setting so that when loading products from OpenCart, the filters for products are removed and loaded from opencart? Since now if the options in the opencart are deleted, then they will not be deleted in the box. Or if you changed the name of the option in the opencart, then a new filter is added to the box, and the old one is not edited 2. There is a setting in the action [file]5539[/file] It loads goods that have changed in opencart by the date date_modificate. Can I make a setting in which it will be possible to specify from which field to take the date of the change? By type as with fields now [file]5540[/file]
