@jayceslesar your thinking something like this, yeah?
```python
def scan_by_tag(
self,
tag_name: str,
row_filter: Union[str, BooleanExpression] = ALWAYS_TRUE,
selected_fields: Tuple[str, ...] = ("*",),
case_sensitive: bool = True,
options: Properties = EMPTY_DICT,
limit: Optional[int] = None,
) -> DataScan:
"""
Fetch a DataScan for the snapshot referenced by the given tag.
"""
snapshot = self.snapshot_by_name(tag_name)
if snapshot is None:
raise ValueError(f"Tag '{tag_name}' does not exist or is not a valid
tag.")
return self.scan(
row_filter=row_filter,
selected_fields=selected_fields,
case_sensitive=case_sensitive,
snapshot_id=snapshot.snapshot_id,
options=options,
limit=limit,
)
```
