Allow an import profile be created based on Luminate's Last Modified By field. Currently there is not a way to filter which constituent updates to import into Raiser's Edge. When exporting an LO Group Query from RE to LO, it updates the Last Modified Date and Last Modified By field on the constituent record, so then Importomatic will pick up these constituent updates to import into RE while no actual change happened on the constituent record. This can amount to thousands of unnecessary imports.
