Sort DataFolders using GetIndexedObjName or GetIndexedObjNameDFR

I am building a table programmatically where waves of the same names are stored in datafolders of varying names.
In this case the order of the waves on the table matters.
In case it helps, I am using liberal folder names.
When I created the folders, I was not super careful about the order I did them.

When I run the bit of code below, I build a table with the waves in the order of the folder creation date.
This is undesirable behavior, I want them sorted alphanumerically.
I can toggle the preferences of the data browser to change the display order, but GetIndexedObjName seems to be insensitive to this fix.
Is there some way to re-order or sort the datafolders in conjunction with GetIndexedObjName such that I can get them in the desired order?

        Edit
        Variable numfolders = CountObjects(tempname, 4)
    for (i=0; i< numfolders; i+=1)
        Tempfolder = tempname + "'" + GetIndexedObjName(tempname, 4, i) + "'"
        SetDataFolder tempfolder
                Appendtotable wave0
        endfor


FYI - my folder names are:
2015_06_08
2015_06_06
2015_06_07
etc...
You can reorder the data folders by dragging all of them out of the parent data folder and then dragging them back in the desired order.

If you don't want to do that, this code shows how to achieve what you want.

Function/S SortedDataFolderList(sourceFolderStr, sortOptions)
    String sourceFolderStr  // e.g., "root:'A Data Folder'"
    Variable sortOptions    // e.g., 16 - See SortList for details
   
    String dfList = ""
   
    Variable numDataFolders = CountObjects(sourceFolderStr, 4)
    Variable i
    for (i=0; i< numDataFolders; i+=1)
        String dfName = GetIndexedObjName(sourceFolderStr, 4, i)
        dfList += dfName + ";"
    endfor
   
    dfList = SortList(dfList, ";", sortOptions)
    return dfList
End

Function DemoCreateTable()
    Edit
    String sourceFolderStr = "root:'A Data Folder'"
    DFREF sourceDFR = $sourceFolderStr
    String dfList = SortedDataFolderList(sourceFolderStr, 16)
    Variable numItems = ItemsInList(dfList)
    Variable i
    for(i=0; i<numItems; i+=1)
        String dfName = StringFromList(i, dfList)
        DFREF dfr = sourceDFR:$dfName
        Wave w = dfr:wave0
        AppendToTable w
    endfor
End

Thanks, I was thinking maybe I was missing some setting or flag somewhere that would simplify this.
Apparently not.
The programmatic solution is the best one as there are a very large number of datafolders.
Thanks for the code snippet to achieve that!
