Is it possible to do it without creating a Stored Procedure

The CREATE TASK statement syntax only allows for a single SQL statement to be specified, and the CREATE … CLONE statement syntax does not permit specifying more than one object at a time.

Given the above, this isn't possible currently. You will need to use an iteration of database names from within a stored procedure call. The same stored procedure can also be used to clean up older dated clones from previous task invocations.

For incorporating dates into a dynamically generated statement within the stored procedure, checkout this question.

P.s. If the underlying goal of the numerous clones is to maintain backups, also consider cross-account, cross-region (and/or) cross-cloud replication for better safety.
