AWS Elastic beanstalk cname with and without www

So, I've got a website running in Elastic beanstalk on AWS and I have a custom domain name which points to it, which is managed in Route 53. When I set up the custom domain initially, I just looked up the IP of the default domain name (xxxx.eu-north-1.elasticbeanstalk.com) and then just created a couple of A records (with and without www) which pointed to that IP address and all was well

Then I discovered that the public IP address of the elastic beanstalk envrionment does not seem to be static. It changes every few months, which means that I had to periodically go and change the A records so they would point to the updated IP. Then I discovered that I could create a CNAME record instead which basically points directly to xxxx.eu-north-1.elasticbeanstalk.com, instead of the IP address . So I created a CNAME record which has www prepended and that works great, even if the IP address changes. However, I cannot seem to be able to create another CNAME record without the www, so that had to remain as an A record which points to an IP address which I still have to update everytime the IP address changes.

Is it not possible to have two CNAME records in the same zone? Both pointing to xxxx.eu-north-1.elasticbeanstalk.com ? How should I go about this?

OK, I think I've figured out how to do this ... I changed the existing A record to an Alias which points to my elastic beanstalk environment. Let's wait and see if works.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
