Can you have shared steps and the enterprise level to be shared across flows

I think I know the answer is no to this question however still need to ask.

Use case is this I want to return a summary of the records processed to NS or any other application through an object. The return field for the summary will be all the same for any of the flows and do not want to have to maintain and add 30 plus flows with added this step and also if there is a change want to make it once and have it be used at the global level. Each flow would be able to call and sub flow that has this sept in it to send to ticketing systems.

I know I can add it to each but as the number of interfaces grow I would like to have sub processes that can be shared across my enterprise

I know not out of the box, but does anyone have any suggestions or may have done something similar

I saw this for the October release This looks like its would resolve my Question. Has anyone worked with it know any more details?

New: Multi-instance flows
Coming in the October maintenance release, we’re introducing multi-instance flows, a more scalable way to manage similar integrations across regions, brands, or business units, without duplicating logic or increasing maintenance.
Managing hundreds of near-identical flows can be error-prone. With multi-instance flows, you define core logic once in a base flow and generate lightweight instances that store only what’s different—such as connection IDs, mappings, or export steps.

Multi-instance flows are available on Professional and Enterprise editions.

Exports and imports can be reused on flows so that one change made to the export/import would propagate to all other flows that have the same export/import. Here is a video of how to do it:
