Yes, this can be done in CasparCG using Flash templates, I did that many times, and sometimes also more complex things. But to explain that in a forum post is quite hard, as it would end up in a advanced ActionScript programming course, and that is not what I have time to do 
So if you have a little budget for this, please post into the new category “Paid Work Available” with a proposal and I would love to quote you, as a few others probably will do also.
Meanwhile see this video. All graphics are done as dynamic Flash templates, that can adapt to different amount of lines etc. Watch at 23:20 for a classification, that can grow in both dimensions, lines and columns are dynamic.
