Possible to get Section Plane symbols (labels) with more than 3 characters?

The current limit is 3 characters, and it’s “cramping my style”, especially with a lot of rooms in a project.

For example, if I have 5 bedrooms, and 4 sections in each one, trying to fit “Bedroom 1 North”, “Bedroom 2 East”, etc, into B1N, B2E, works for a moment, until I need Bathroom 1 North, Bathroom 2 East, and I’m screwed.

Is there any way to get SP labels with a couple more characters?
