Adding comments in cube view in front of calculated row

I’m working on a Cube View where one of the rows is a calculated row (using CVR / GetDataCell to derive the value from other rows). The users want to be able to enter comments directly in the Cube View in a column that appears “in front of” (or next to) this calculated row.

Has anyone implemented comments or text entry against a calculated row like this?

Specifically, I’m trying to understand:

• Whether it’s possible to add comments to a CVR-based calculated row (where the numeric data is not stored, only calculated at runtime).
• If not directly, what design patterns are recommended?
• Any examples of Cube View layout or member/filter tricks that let you show a calculated row and a comment entry cell side by side for that row.

Environment is OneStream version 8.5.3, and this is a standard Cube View used for reporting (not a custom dashboard).

Thanks in advance for any ideas or examples.
