SSL server cert import without CSR process

Hello SSL experts!!!

I understand that the standard process to setup SSL is to generate a CSR and then import the response. 

However, my company's IT folks have what they are terming a "global SSL" signed cert for *.<domain>.net"

For other internal IIS-based web applications they were able to import this certificate ~directly. 

In order to not have to purchase and maintain another signed cert, they would like for me to see if we can do the same thing with our ABAP ERP system (SAPKB73103).

I'm thinking maybe sapgenpse might have some tricks to allow this??

Thanks for any guidance you can provide.
