Specify shell or allow setting all jobs to automatically source a file/profile?

[MostHated]

Hey there,
I seem to be having a bit of an issue finding a reliable way to access environmental variables and functions from jobs. I see that the jobs return back $SHELL as /bin/sh. Is there some way I can make all jobs run under a different shell (such as zsh) so that it can automatically pick up my .zshenv file or if not that, at least pick up the /etc/bash.bashrc or something along those lines, straight from the cmd line within the job file so that I don't have to make each job individually source it?

Thanks,
-MH

I just thought of this, so I wanted to post it while I was thinking of it. Being able to have settings such as the ones below would be awesome.

prefs:
  shell: /bin/zsh # Set default shell for all jobs
  source: $HOME/.jobberenv # Default source file for all jobs

jobs:
  myjob1:
     cmd: $HOME/scripts/job1.zsh
     source: $HOME/.job1env # Source for specific job in addition to the default source
     time: '*/30 * * * * *'  
     onError: Continue 
  myjob2:
     cmd: $HOME/scripts/job2.xsh
     shell: /usr/bin/env xonsh # Shell for this job, overriding default shell above
     source: $HOME/.job2env # Source for specific job in addition to the default source
     time: '*/30 * * * * *'  
     onError: Continue
