Joe,
you can't do that and you shouldn't really want to do that. Please read Tug's response for your options.
I understand you are curious about my two CCSE renewals. I got the first one for attending a CPX pre-conference training and the second one for completing two Check Point accreditation exams.
Please note: CPX training attendees nowadays only receive six months extension towards extending a current CCSA, CCSE or CCSM certification. If you aren't already signed up for CPX360 in Las Vegas, Feb. 6-8, 2018, hurry up > register for the post-conference training on Feb. 9th and have your CCSE extended for another six months to have more time to thoroughly prepare for your R80 CCSE Update (156-915.80) exam.
Thanks,
Danny
