Help!!! Fastest way to define contacts?!!

Hello,

I have a model with multiple components that consists of a outer case and several internal components, 

I want to define type 7 symmetric contact for all of them because I think there is a possibility that each one of them comes into contact with each other, 

but right now I have to define a lot of contacts for each pair of components, for instance, green´s nodes with blue's elements, green´s nodes with orange´s elements, etc. This is really time consuming.

Is there a way to define type 7 for all possible combination of components? An option where you insert a bunch of components and the program would define type 7 contact for you?

(I have seen something similar in this tutorial, on step 9.2 it defines a single type 7 contact which includes 8 components, which seems insane to me https://2021.help.altair.com/2021.2/hwsolvers/rad/topics/solvers/rad/front_impact_bumper_hm_r.htm#ariaid-title11)
