Javascript Google脚本动态数据验证

我有以下脚本。此脚本接受名为ranges的活动工作表，并将其用作动态数据变量。但是，我想让它从另一个独立的表中获取命名范围，并使用该数据，而不是在同一个表中

这可能吗

function depDrop_(range, sourceRange){
    var rule = SpreadsheetApp.newDataValidation().requireValueInRange(sourceRange, true).build();
    range.setDataValidation(rule);
}

function onEdit (){
    var aCell = SpreadsheetApp.getActiveSheet().getActiveCell();
    var aColumn = aCell.getColumn();
    if (aColumn == 4 && SpreadsheetApp.getActiveSheet()){
        var range = SpreadsheetApp.getActiveSheet().getRange(aCell.getRow(), aColumn + 1);
        var sourceRange = SpreadsheetApp.getActiveSpreadsheet().getRangeByName(aCell.getValue());
        depDrop_(range, sourceRange);
    }
    else if (aColumn == 4 && SpreadsheetApp.getActiveSheet()){
        var range = SpreadsheetApp.getActiveSheet().getRange(aCell.getRow(), aColumn + 1);
        var sourceRange = SpreadsheetApp.getActiveSpreadsheet().getRangeByName(aCell.getValue());
        depDrop_(range, sourceRange);
    }
}
