This feels like a bit of a bug... basically that field (and that field alone, in that section) cannot be dynamically set, it has to be a raw string. I believe this is a known issue, but you might want to confirm it with Support.
As for workarounds: "Row Overrides" on Columns are superseded by "Column Overrides" on Rows, so you could reach a degree of reuse by having a template (Shared) column with static override settings, and then applying specific overrides on rows in the actual Cube Views.
There might be other approaches if you need these CVs in Dashboards, where Extenders may (or may not) be of help.
