Can I create Shared Table Architecture in frappe ERPNEXT?

Is there any method to create a global shared table for Multitenant sites ?
It is a crucial feature for managing a unified Customer Relationship Management (CRM) and Items or Global Authentication table across multiple tenants in Frappe.
I have performance based issues with Master-Slave and Event Streaming features.

It’s very important feature for query optimization, performance related task, ease the report building process. Please let me know if it already exists.
