In a SW drawing, I have multiple horizontal magnetic lines.  I would like them aligned with each other.

In my example, I would like to align the top row, #27 with #20 and #19, and with #28 and #26, and I would like to align the bottom row of each set,  #29 and #33 with #22, 24, 23, 21 and #30, 31, 32.

How can I do that?
