shortcode exec php

i refer to https://premium.wpmudev.org/forums/topic/how-do-i-make-a-multi-site-global-shortcode?utm_expid=3606929-67.-MP1PYYzS_6mvlSTiltv6Q.0&utm_referrer=https%3A%2F%2Fwww.google.com.au%2F

i understand that shortcode exec php is not available as a plugin anymore. can you suggest an alternative? my objective is to be able to edit/update contents across my multisite network in one hit.
