+- Instead of specifying a path provides an Excel Package object (from `Open-ExcelPackage`), using this avoids re-reading the whole file when importing multiple parts of it. To allow multiple read operations `Import-Excel` does NOT close the package, and you should use `Close-ExcelPackage -noSave` to close it.
