Following up on this question I asked some time ago, I am facing a similar scenario, but for the life of me I do not seem to get it right with the solution provided in the question above, and I have no clue...

The following is a MWE, all I want to do is to merge rows vertically (multirow), so that "Preventative impacts of RA" and its corresponding "G5 vehicle UVB 40h" span 4 rows, and "Preventative impacts of RP" and its corresponding "G5 vehicle UVB 40h" span 3 rows.

How should I do it? Many thanks!!
