Deal Split Owner ID to be included in Reports

[imrehg]

I'm making a report regarding deal splits (since they don't seem to be available trhough the API, which is a different question).

When I add the "Deal Split Owner" as a column, it only includes the user's name, and not the ID.

This is especially confusing as the propery info shows that:
Property internal name
[DEAL_SPLIT.hubspot_owner_id]

On the flip side, other potential colums like "Created by User ID" has both name + id in there, and much more usable.

Is it possible to get a field for the Deal Splits reports, that would make the actual ID accessible?

(this is especially important since there are no other ways to get this data, given that it's not available through the API)
