title: how to avoid unnecessary check of reducer switch case
body: <p>I got two reducres that each one will handle a slice of state</p>
  
  <p>my problem that those two contains huge switch case, or i found that redux is calling all reducers so each huge switch case gone be called ( because i'm using combineReudercs ) </p>
  
  <p>does it possible to target a specific reducer from the dispatch to avoid uncessary check of switch case ?</p>
