Is there a faster way to create SPF text for multiple subdomains?

Goodevening everyone.
We’re creating everyday many subdomains (each subdomain for each client) for the same domain. For each subdomain in order for emails to work (as far as we realized) we should be creating an SPF txt and a PTR” (PTR) Record.
The code is the same but subdomain only is changing. Is there a way to make something like *.maindomain.com and take this setting for all domains ?

Thanks in advance

The wildcard TXT record should work. I just tested it on a domain that previously had no SPF records.
