Hello Node-RED community,

I have a question regarding implementing multi-tenancy in Node-RED. In my current setup, I have different sub-flows dedicated to separate tenants. These sub-flows handle specific processes, such as placing orders to platforms like Amazon, with each tenant having unique requirements.

For example:

- **Tenant 1** : "Bob Tenant"
- **Tenant 2** : "Sam Tenant"

Currently, I route the main flow to the appropriate sub-flow using a switch node, based on the `tenantId` received from a request. While this approach works well for a few tenants, I’m concerned about scalability as the number of tenants potentially grows to 1,000 or more. Loading all sub-flows at once is not efficient or practical.

To address this, I’m looking for a way to intercept Node-RED HTTP-based requests that trigger the deployed flows, allowing me to dynamically load and execute only the desired sub-flow at runtime based on the `tenantId`. This would help optimize performance and manage resources more effectively as the number of tenants scales up.

Is there a recommended approach or any advice on how to intercept these HTTP requests and dynamically load sub-flows at runtime in Node-RED? Your suggestions or insights would be greatly appreciated!

Thank you in advance for your help!
