Pkcs#12

I’'m trying to get Spark working with PKI. My company is using PKCS#12 for their logins. I’m using the Spark 2.6 Beta version. Selecting the PKI tab under Advanced, I only see JavaKeystore , PKCS#11 and Apple KeyChain. Is there a plugin for PKCS#12? Also, when I selected Use PKI under Advanced Connection Preferences the Password box still appears on the login screen even though there should not be a password required. The Login button is grayed out if a password is not entered.
