about DNS record

I have many subdomain or DNS update in ISP..

My domain which host in ISP, so everytime if any DNS update, I need ask ISP to do.

But as I have so many DNS update....can I have a way to check all my domain DNS record?
or ISP only can check?

DNS zone file 睇晒。。。

咁多 subdomain,  點解唔自己在 domain registrar 到 manage? 通常都有 portal 自己處理到。。。
