Share 'High Rise Packs'

I wanted to know if any depts are using a 2 1/2" to two 2 1/2" outlet gated wyes for the hookups (to the standpipe outlet) to allow for one person to control the standpipe discharge for 1st and 2nd line and cut down on lengths needed and people for the second line usually hooked up two floors below? For 2 1/2" lines of course. Thanks Ian
