Problem in forwarding traffic of all subdomains and domains

Hello
I would be very grateful if you could help me
I redirected a series of domains to my load balancer through my DNS server
I don’t have a problem with these settings. My problem is that I have to add the same operation one by one for each subdomain, which is too much. Is there a way to automatically do the same for all wildcards and not add each one?
