Can I merge two apple IDs?

I currently have two Apple IDs. One was setup when I bought my first Apple device - iPad, to access iTunes and other payed subscriptions. The second was set up when I bought my Mac to sync my account over iCloud. Is there a way to sync these two accounts? I recently signed up for Apple One thinking I would save money on my subscriptions, but I am finding out this this is costing me more as I am paying for storage twice and only using one location.
