Storing sequences in grasshopper

Hi, I have completed the grasshopper course by Andres and I would appreciate advice on a couple of things.
If I have a sequence of commands ( eg from a curve or curves through to multipipe ) and I name them as a group, is there a way to recall that group as a command in a different gh document ?

I know that I can copy and past them but i would like to be able to store them as custom commands

you could use Cluster, you can name them, put an icon … and use them like a component.

will the icon show up when I start a new file and if so where will it be in the toolbox ?

Try to find tutorial, discussions on this subject.

… and surely many other ressources.

thank you
