Is your feature request related to a problem?

When I use graphrag to parse some excel files, then checked the KGs, some look likes good but also have some miss important relations between entities.

Describe the feature you'd like

Can you add support for modifying the graph directly? Alternatively, it supports importing and exporting graph files, such as parquet, which can be modified using neo4j and then imported for use.
