Assign package to a configurable option

[adg273]

Does anyone know if you can, or how to assign a hosting package to a configurable option. 

For example, say you have a hosting package, but you have the option of Linux or Windows. Is there a way of having the two options as a configurable option, so the one a customer selects is the package type that WHMCS automatically creates?  Rather than listing both the Linux and Windows variants on the services page.
 

I know I can put it in, but have to manually create the package. This isn’t a viable option for me. I’m looking for WHMCS to create the right package type based off the configurable option selected.

 

thanks for any help anyone can provide
