Updating Smartsheet Summary Field Pick List values

I am currently updating column pick list values in sheets with an API call to keep the options in sync with the source.

There is now a need to apply those same pick list values to a summary field pick list options list.

• This post confirms how I update a sheet column, which I am doing successfully

However, looking for same keywords and adding 'summary' results in nothing. Has anyone been able to do this?

I am successfully pulling the summary field values curl https://api.smartsheet.com/2.0/sheets//summary/fields -H "Authorization: Bearer "

Any help would be appreciated

Adding/Updating summary fields by curl or by the SDK works, refer to the documentation : https://smartsheet-platform.github.io/api-docs/?shell#add-summary-fields
