Hi marcorhino, there currently isn't any way to do one blend that covers more than one edge along one side. That's definitely something that needs to get tuned up in the future.

For V1 one way you can work around it is to split up the other longer edge into the same number of pieces.

To do this, select the edge and then run Edit / Trim, and then pick the "Add trim points" button, and click a trim point at the spot you want to split the edge at.

Then you can pick pairs of smaller edges that match up for blending.
