I see that there was a bug request closed for this but no explanation was given other than "that's the way it is". It is something that excel supports and it is a lot easier than copying all of the data into a massive rectangle. Thanks https://bugs.freedesktop.org/show_bug.cgi?id=87758

It sounds plausible as an enhancement, so this will live in NEW until someone picks it up to work on it or decides to reclassify it Status -> NEW
As of LO 7.3 it is currently possible to add multiple ranges in "By changing cells" field. You simply have to type ";" to separate each range. For example: $D$8:$D$37;$E$8:$E$37 Contains 2 ranges $D$8:$D$37 and $E$8:$E$37. I have just tested and it works fine. So this is WFM.
