Is it possible to have different graphs for the same industry over the years?

Or if not is it possible... for a new industry with different graphs to replace the old industry with the old graph in the same place?

Basically what I want to achieve is that, for example, a 1950 factory looks like a factory from that time, but in the year 2000 it will not continue to be the same old factory but rather a modern one.

ECS has this feature. In particular, the factory will gradually switch to one of four different designs, depending on the current year.
