Revit can do multilevel text like this:
1. text text
2. text text
A. text text
B. text text
a. text text
b. text text
C. text text
a. text text
b. text text
• text text
But I would love the ability to do it like this:
1. text text
2. text text
2.1. text text
2.2. text text
2.2.1. text text
2.2.2. text text
2.3. text text
2.3.1. text text
2.3.2. text text
2.3.2.1. text text
