Day / night mode for multiple DDIs

If I have lets say 3 DDI’s and I want to manually put the system on night mode would I have to enter *280 for the first DDI then *281 for the second and then *282 for the third?

I assumed that I would be able to set up three different Day/Night controls that could all be activated with the same code but this is not possible as when you have set up the first using *280 and then try to set up the second the 0 is removed from the index list.

Is there a way to manually put multiple inbound routes on to night mode with just one code?

It is useful to be able to manually put different departments onto nightmode at different times but it would also be good to be able to put all departments onto night mode at the same time with just one code.

any ideas please?
