Change time in Transport. Ability to change by group or not?

Hi everybody !

I’m searching a way to modify quickly all the bindings positions in my timeline to adjust my dmx lignts. I have a little latency… few milliseconds I think.

Is there a way to apply in one time, a bit backward or forward, the positions of a group of bindings ??? That would be excellent to do that and so I could get my lights more precise.
