Plugin before stereo out without using a rack

[unguitar]

hi,

I have 9 racks which outputs all go to Master Stereo Out.

I would like to have a filter and a limiter just before Master Stereo Out.

Is making a new rack which gets all the outputs from the 9 racks, has the filter and limiter and Master Stereo Out as an out the only viable solution or is there another way, without using a rack?

thanks,
Luca
