Multiple Flow Inputs

I'd like the ability to add multiple inputs to a flow at the beginning at least, like a hopper so it could be something like...

This would allow us to only have 1 flow for Manual Sync or Sweepers

The logic could work either like the route shape with filtering OR like the branches shape and work sequentially.

This would cut down 3 existing flows to 1, but most importantly ensure parity across all 3 flows, at the moment if a change is made to a flow then the sweepers are easy to forget to update and they become out of sync.
