Do you have an example?
There are four steps that I run as preparatory steps

The way I have tried to have all slaves to run the same steps is to
have a *builder
per slave* and have after these builders have finished their work they
trigger a dependent scheduler.
This approach is not exactly what I want since I would have to add code
every time I want to add a new slave (to add its unique builder) and it
would mean more columns on the waterfall.
Aside of this, if one of the slave has not finished because the slave was
not connected (for whatever reason), the next dependent scheduler will not
be triggered.

What about if I subclass a builder?

I could try to ask which slaves are available and assign each one of them
the same build object and then that slave could get assigned the not
preparatory steps.

self.slaves seems to contain the list of slaves that are related to a
builder

The attached image contains the setup with only one slave
