How to join two visas appointments?

[AMDsn]

Greetings,

I want to apply for B1/B2 VISA for some vacation in addition to applying for another J1 visa to compliment my education.
I am ready to go and schedule an appointment for the B1/B2 VISA as my papers are ready, Can I join the J1 appointment when finishing my paperwork to that B1/B2 VISA appointment ??
How can I do that if it's possible?
