The process of autolyse with sourdough starter is called fermentolyse. In this scenario, you can add a sourdough starter with flour and water before letting it rest (1 hour in most cases). In this case, fermentation will also take place with autolyse. This could be counterproductive.  But if you are baking in very cold weather, where it takes longer for the yeast activity to kick in, you can surely go for this kind of resting.
