String slice into specific schema

[tallen42]

The struct I have in mind is

type Team struct {
 ID uuid.UUID
 Members []string
 (other Team fields)
}

Which would break out into the following schema:
Table "team"
ID UUID primary key
other fields

Table "team_members"
ID UUID
Member string
Composite Primary Key (ID,Member)

Is there a way to do this?
I thought about making a named Member type that was just a string, and then having a slice of that, but I think that ends up being the same problem. Having a struct Member that just has a Username string would end up with 3 tables probably, which seems excessive. This should be able to be done in two tables, I just don't know how.

Any advice would be appreciated, thank you!
