I *think* this should work though if you set up the right job dependencies.
very simple example:

job1 is "when:manual", job2 has "needs: job1", job3 has "needs: job2".
Nothing runs at first, if you trigger job1 it'll cascade down to job 2 and

The main limit you have here are the stages - where a job is part of a stage
but does not have an explicit "needs:" it will wait for the previous stage
to complete. That will never happen if one job in that stage has a manual
dependency. See this pipeline as an example:

So basically: if you set up all your jobs with the correct "needs" you could
even have a noop stage for user interface purposes. Here's an example:

It has a UI stage with "test-arm" and "test-x86" manual jobs. It has other
stages with dependent jobs on those (cascading down) but it also has 
a set of autorun jobs that run independent of the manual triggers. When you
push, the autorun jobs run. When you trigger "test-arm" manually, it
triggers the various dependent jobs.

So I think what you want to do is possible, it just requires some tweaking
of the "needs" entries.
