A question on How to remove the white border of polygons using QGIS was asked yesterday, and I voted to close the question as a duplicate to another question that has an answer. However, sometimes there are more than one question that can be linked to the OP as exact duplicate, but with a better solution. But since we only have to provide one link as a duplicate question to the OP, I added another solution in the comment.
I understand that duplicate means an exact question asked two times (with different phrasing, of course), but sometimes it has more than one possible solution.
Is there a way to add more than one link to an OP when marked/voted as Duplicate? In other words, can the system be expanded to give more than one option when adding a link to a related question.
