Why not create them by opening your excel part family? (right click on your Excel part family table)
To do this, you select your first column that corresponds to your configuration name, you choose the cell format = standard, then you can apply a formula in this cell to fetch values from other columns for example. And then you can stretch this formula to apply it to the next cell.
Here the standard format is to be applied from line 3 to 16 only and all lines not filled in complete must be deleted at the risk of causing errors, or even leaving the file without saving it.
From your parts family list in Excel, use the concatenation function "=concat("B3"; "-"; "C3"; "-"; "D3"; "-""E3") in your A3 cell, and then repeat this function on all "Name" ("A3"->"A16") cells. In this way, Configuration Manager will use this feature for all of your new configurations. (Personal note: if you can, avoid keeping the dots (.) in the Configuration Names, it may be a source of problems...) You also had to delete all your "0000" lines
