I see yes.
The thing is that in this case, the sheet includes references to other files that you need to clone as well.
For example, the filters are defined in the xl/tables xmls. So you need to clone this as well and update the references.
I know its tedious work, but we don't have API that could do this for you at this moment.
You gonna need to unzip the xlsx and check the references in worksheets/sheet*.xml and clone the references xmls as well.
