Map Primary storage to host.

[Halloesnith]

I am using cloudstack 4.15.1 and 2 KVM hosts. I am on a testing phase and I 
have created two primary storage(p1, p2). All I want to know that is it 
possible to map a primary storage to one hosts via tags or others. If user 
creates a VM in host 1 them his primary storage is allocated from p1 and if a 
user creates a VM in host2 then his primary storage is allocated from p2. I 
have found that service offering's host and storage tags is useful but I want 
to directly map all the vm's when created to their respective primary storage. 
Just testing for knowledge purpose.

Thanks in advance.
