Is there a way to bring other stored flows to use as a Component?

[sjsinju]

There is a simple flow with LLM saved "SimpleLLM"
"Input - OpenAI LLM - Output".

Then, I create a new flow "An agent with simpleLLM"
In this case, I want to make flows with a component from a saved simple flow "SimpleLLM".

"Input - SimpleLLM Component - Output"

But now, I think it seems not to have any way to load saved flows as a Component.

I know the only way to resolve this now is a "group mechanism" or "custom component with ToolCallingComponent".
But I want to use the flow directly as Component.

Is there another way or the plan to support this?
