Is it possible to reset DLC?

Been playing FE Echoes and dumped some of the DLC, specifically Mila’s Bounty 1-5, which gives me a few single use items and some currency to use towards forging and whatnot a single time per DLC. Was just wondering if it was possible to reset the DLC in a way where I could so I could get additional copies of said items. Many thanks in advance for any help.
