Viscosity client p12 certificate

[tttrntt]

We use the user certificate's password to prevent people to install the client wherever they want.
The viscosity client for the mac doesn't use that certificate although the settings are "Certificate with External Auth" and "Use a password to protect the pkcs12 file contents or key in Viscosity bundle." is enabled.
Is there any way to make the use of the users pkcs12 certificate mandatory and include it in the viscosity client?
Thanks.
