I am typesetting a text with line numbers in the margin and am interested in combining them if two should end up on the same line, dividing them with a comma or something like that. With the code below, the first line of the output contains an overlapping "1" and "2" in the margin. I would like the "1" and "2" not to be overlapping, nor to be stacked like \setupmargindata[stack=yes] would get me, but rather to automatically combine those that would overlap to get something like "1,2".
Is there a reliable way to implement this? Any help would be appreciated!

\inmargin{1}Now we are engaged in a great civil war. \inmargin{2}We are testing whether that nation or any nation so conceived and so dedicated, can long endure. \inmargin{3}We are met on a great battle-field of that war.
