How about a stringgrid to display the Values an editable TStringList which has a blank string for each row in the dataset, made up of your keylinks column value and the quantity in the format KeylinkValue='' (i.e. empty string).

When you are ready to construct your INSERT, match up each selected row with the Name[s] item a test/convert the quantity. You can set up the stringgrid and dock it so that it just looks like another column of the ib_grid.
