Consolidate Reference Data table entries into one entry via Change Identifiers or similar new process

As a Planning/Finance Administrator, I would like Planning (the tool) to to find and replace and, where appropriate, consolidate (the new feature) indicated identifier for all plans across time, regardless of whether the plan is open or closed.

The current Change Identifier feature help documentation is available at the link below:
https://help.apptio.com/en-us/it-planning/planning/change-identifier.htm

This request would enhance the feature to "consolidate" existing entries in Reference Data tables.

If the Change Identifiers feature of Planning cannot be adjusted to accommodate this request, then please consider adding a new option to perform the consolidation.

For example, the following entries are present in a custom "Project Request" Reference Data table's [Name] field (aka the identifier for the table):
I03195||EMEA TV Playout Transition
I03195||EMEA TV Playout Transition - Application
44643||I03195||EMEA TV Playout Transition - Application
44643||I03195||EMEA TV Playout Transition - Applications

We would like to consolidate the four entries into a single one with the following new [Name] value:
44643||I03195||EMEA TV Playout Transition

When submitting the Change Identifiers form for the above change, the following error is displayed:
Errors
The new identifier is a duplicate of a previously published identifier. Please change the identifier for the previously published identifier, then try again: Name (1) (Excluded in Help File)
44643||I03195||EMEA TV Playout Transition

In the earlier example, the outcome was primarily driven by name changes for the same project. Consolidation could also collapse unrelated records. For example, an organization's leaders decided to collapse 3 projects into 1 project and want all historical reporting, budgeting, and forecasting to appear under the 1 project. Today, that type of consolidation cannot happen.
