The issue is the difficulty of interactive excel import, that is, when the user iteratively modifies the edges and nodes in Excel.
It is currently cumbersome, any time the excel file is reloaded, to re-enter the data source fields in the import dialog.
There should be a one-key reload option that would read the excel file, detect any change to the node table and to the edge table, adjust the number or rows automatically, keeping the columns per the headers.
Thanks
