I dont know if this is possible in the form generator, but seems StringFormat could solve this.

          - `{StaticResource <ResourceKey>}` - Gets the value of the specified resource key, but does not update when that value changes.
          - `{FileBinding <FilePath>}` - Reads the text content of specified file path, and updates automatically when the file content changes.
          - `{File <FilePath>}` - Reads the text content of specified file path, but does not update when the file content changes.
          - `{Env <EnvFlag>}` - Returns whether the specified flag key exists in current form environment, and updates automatically if that flag is added or removed.
          - Contextual resources such as `{Value}` and `{Argument}` inside validators.
          
          ## Syntax Specification
          
          A dynamic resource is declared as follows, where brackets indicate optional content:
          
          `{[^]<ResourceType> [']<ResourcePath>['][,<Padding>][:<StringFormat>][|<Converter>]}`
          
          The optional leading caret `^` indicates that the contextual resource should not be synchronized with the source. For example `{^Env ReadOnly}` checks for the presence of the `ReadOnly` flag only when the form is constructed, and will not return an updated value even if that flag is later added.
          
          `ResourceType` can be one of the listed resource types above.
          
          `ResourcePath` specifies the argument of the resource type, such as the name of a property or the key of a resource. The resource path can be wrapped in single quotes, which is useful if the path has unconventional characters, e.g. `{File 'C:/Program Files/my file.txt'}`
          
          `Padding` can be optionally added, which is applicable when the value is represented as a string. For example `{Binding Name,-30}` will display the `Name` property using 30 characters and will be padded to the left. A positive value indicates right padding.
          
          `StringFormat` can be optionally added, which is applicable when the value is represented as a string. This parameter will be passed to the `ToString(format)` method. For example, `{Binding Year:yyyy}` displays the DateTime property `Year` in `yyyy` format.
