Describe the feature

Elevator callers placed adjacent to one another in a rectangular prism should join up into a single elevator caller multi-block, rendering floor names across the entire multi-block, instead of repeating them on each individual block.

Reasons why it should be considered

Currently, if you have enough elevator floors to cause the caller to display a second column of floors, you end up with a very limited amount of space for each floor name before they begin overlapping with the adjacent column. This is probably fine if you just want floor numbers, but if you want to put any kind of description or actual name per-floor then it quickly becomes an issue. Here's an example screenshot for the basement elevator of my current base:
