How do I use Gremlin to attach attributes to Vertices?

[Common-zhou]

Describe the feature:
Hello, I am currently using Gremlin to implement some queries. I would like to ask if Gremlin has a way to attach attributes to Vertex?
For example, appending to a Vertex (A) on a path is based on a property of A Vertex (B).
I've seen a way to add attributes, but it's inefficient and probably not for me.

Describe a specific use case for the feature:
For example, I need to calculate the score of a Vertex for subsequent queries.Calculate a 1 - > 5, 2 - > 8...
Then in a subsequent query, I need to pull out the property based on that Vertex and assemble the result
