UI - Text attributes within string?

Unity Engine
1

Is there a way give text attributes within a string?

For example if I have the string “I want this to be bold”
would I have to break the string up into 3 parts or is there some sort of markup in the new UI system?
for ex "I want this to be bold?

Found what I was looking for, calling it “Rich text”

There are only 4 tags though, would love to see some expanding here, this is very helpful!
