Should there be a field for which source the collision is present in?

In the collision record, does it make sense, does it add value, to add a field that describes which source (NCBI, HGNC, or Ensembl) features that collision for that gene? For example, in the VH collision record, only NCBI Info uses VH as an alias and therefor the collision VH is only present in NCBI.
