Physics Simulation Start Offset

Currently, my Rigid Body Sim is starting to calculate at Frame 1, but what if a shot always starts at frame 1001 or we want some frames before a shot - then it gets complicated.... We can use the deactivate or animate function on the rigid body sim, but we have to copy that to every object and we override with that the specific settings for each object. Is it possible to make an Input field to offset the global simulation start?
