Question about excluding subfields

[smluke2]

Henry,

In the TOML file, will the script work if we don't list subfields (but the entire MARC field). For example:

[[mapping]]
key = "Contributor"
matching_marc_fields = [
"700",
"710"
]
delimiter = "||"
existing_data = "keep"

Would this pull all the content from both of the listed fields?
