SharePoint List Update Item card is unusable when there are multiple types of List fields such as multi-value. Current design requires all required fields to be re-associated as dynamic content and unable to pull dynamic content for multiple values.
Copy the Sharepoint - "Set content approval status" card for Sharepoint - "Update Item" card but allow selecting one or more SharePoint custom field to be updated. Update Item card will at least have these fields: - Site Address:
- List Name:
- Custom Field to update:
- New Custom Field value:
- <option to +add more custom field to update>
The update logic will look for the reference ID field and then perform update only to the custom fields selected with the new value.
