How to merge vertical cells

I need to merge vertical cells, i know that is possible via service studio to merge horizontal cells and i try the same way with vertical cells but doesn't work, the merge is disable.
Is it possible merge vertical cells with service studio?????.

Thanks in advance,

Checking Documentation about Mergin Cells (, seems that "You can only merge adjacent cells that are on the same row.

One Solution for that :
You can extend the RichWidget and add one webblock to do that as CellMerge_Right does.
See .oml as an example. This solution can be improved!
