Anyone else having trouble using blackjack chests?

I have rebound my buttons, on PS4, so that my d-pad selects weapons and triangle swaps firing modes. This works so much better, but means I can’t spawn a vehicle without entering the catch-a-ride menu, or buy ammo without entering the vending machine menu.
Now, I come across these new chests, in the DLC, which I love. It’s an awesome idea. BUT, I can’t do anything but hit each time, unless I go into the menu and rebind my buttons every time. Why isn’t this kind of context sensitive input bound separately?
Or let me bind it to “Hold triangle” or something?

Anyone else having the same issue?
