Performs partial updates on multiple program templates simultaneously using JSON Patch operations. This is more
efficient than individual updates and allows updating specific fields across many templates without replacing
all data. The operation is performed asynchronously and returns operation IDs for tracking progress.

Key Features:

• Updates multiple templates efficiently in a single API call
• Supports partial updates using JSON Patch operations (add, replace, remove)
• Updates specific fields without affecting other template data
• Processes updates asynchronously for better performance
• Returns operation IDs for tracking update progress
• Maintains referential integrity across template updates
• Creates audit trail of bulk modifications
• Does not affect programs already created from these templates

Authorization Logic:

1. User must have a valid JWT token with management scopes
2. User must have program update permissions
3. User must have permission to update each specified template

Usage Example:

Bulk update multiple templates to standardize manager assignments, adjust planned durations across
seasonal templates, or update custom property values for a category of templates.
