I have certain elements in some rooms, to which I want to add parameters related to that room. Everything else is solved except the issue of creating a list of rooms which contain element with same index as those elements.
Looking at the following image, I would like to get Room list with only those rooms which have that element. So if I have 2 or more elements in same room (this creates sublist of elements) that I have that room same number of times in the list on same index as element.
I hope you understand my point.
