Use of dummy salesperson to derive accounting in Financials

Summary:

What are people's experience with using dummy salespeople configuration as a shortcut to derive accountings segments in Fusion financials?

Content (please ensure you mask any confidential information):

In E-Business Suite, there is a quite common workaround / shortcut to achieve some auto-accounting segment derivation using the sales person field on various transaction, where this was used to only to derive accounting, not to actually calculate sales credits.

In Fusion, it's a bit more complicated because the sales person needs to exist as a Resource in CX, but it's still possible to do this.

Has anyone done so? How has it worked out?
