IIS v8.5 unable to Add Site Binding for more than one site with HTTPS under one webserver.

[Senior System Engineer]

I'm using IIS 8.5 on Windows Server 2012 R2 as the webserver.

I have multiple websites running with approximately 90+ Virtual Directories as I can see from the IIS manager.

What I have done:
1. Import the Wildcard SSL certificate *.domain.net to the webserver (PRDWS200-VM) and it is select-able on the Add Site Binding window.
2. Create the separate Virtual directory inside the C:\Inetpub\wwwroot\Product1Launching



I don't want to cause any production issue, but how this is what confuses me:

Error is:

[FONT=inherit][SIZE=3]---------------------------
Add Site Binding
---------------------------
At least one other site is using the same HTTPS binding and the binding is configured with a different certificate. Are you sure that you want to reuse this HTTPS binding and reassign the other site or sites to use the new certificate?
---------------------------
Yes   No

After clicking NO, the product website is only accessible via HTTP://product1.domain.net
The goal is to be able to publish the website as HTTPS://product1.domain.net without causing any other website to break due to pressing YES on the previous prompt?

Does one IIS 8.5 Webserver can only have one website with https instead of multiple?

Thank you in advance.
