In a wash sale transaction do I need to change the date acquired of the security acquired within 30 days of the 1st transaction to the date of the 1st transaction?

I purchased 1 option contract  on 8/17/18  and sold it for a loss on 8/23/18.  On 9/14/18 I purchased another option contract for the same stock.  The loss on 8/23/18 is disallowed  and  added it to the cost basis for the 9/14/18 purchase.
