bounding box

Dear all, I am using the python API.  When downloading data like esa world cover, does the API always just give the whole tile where the area of interest lies in? (multiple tiles when the area of interest intersects with more tiles?) For my use case, I want to pass a geometry like the adiminstration boundary of a region and only get the data within this boundary or pass a bounding box and only get the data within the bounding box, but not the whole tile. I also opened an issue over on github (https://github.com/VITObelgium/terracatalogueclient/issues/6). Moreover, when the area of interest intersects with multiple tiles, I want to have the data already be processed and not have multiple files which I have to merge. Is this possible? :)
