is there a way to change the storage class of newly uploaded objects in an AWS S3 bucket?

Question

I am using nakivo as a backup solution, and one of the backup repositories is an AWS S3 bucket for off site storage, i would like to save on cost by making sure all of the data that is being stored in the bucket is stored in the Standard IA storage class, is there a way to accomplish this without using lifecycle rules ? (since the minimum storage duration before moving an object to the standard IA class via a lifecycle rule is 30 days, and i would instead prefer the objects to be deleted after 30 days). would it for example be possible to regulary copy the objects in the bucket, saving those copies in the standardIA storage class and delete the objects in the standard storage class ?
