field group name on a form cannot be a variable to support multiple language

[AlanSkyNet]

On a form, I can have a group of fields :
searchCase: {
name: 'searchCase',
header: stSearchCase,
focus: -1,
style: gstyle,
fields: {
'Values': {
type: 'group', span: -1,
attr: 'style="width: 100%"',
style: gstyle,
fields: [
{ field: 'keyword', type: 'text', html: { label: stKeyword }},
{ field: 'casecode', type: 'text', html: { label: stCaseCode }},
]
},

I want the 'Values' entry to be a javascript variable in order to set it with a different text depending on user language.
it could be a new attribute name that overrides the 'Values' group name.
