Resupply method from one location?

[Accel Lex]

I thought the Terrabyte, Mobile Base, Nightclub, and another one said that you could supply your businesses from that one spot. I figured it meant Resupply. Or be able to check the supply levels of all businesses from one spot. Everytime I visit my Coke and Meth place, they're always out and I didn't get a notification. I get a text mabye twice before, but that's it.
I heard Arcade has something like that, but I don't know anymore.

Is there a way to manage all/more than one business at a time?

Being able to buy supplies for bunker, coke, etc.

Arcade does that with the master control terminal
