It would be nice to have additional option in the multichannel pipline configuration to specify custom parameters to pass to the tirgger job.
The problem we are facing right now is next. We have a lot of multibranch projects for different apps:
But for most of those apps the OnDelete trigger job performs the same steps. The only difference is that we need to cleanup resources according to the app name. We want to have only one OnDelete job for all those multibranch projects but provide parameters together with SOURCE_PROJECT_NAME param to indicate for what app we've triggered job.
Also it might be useful to pass other custom parameters from the upstream job.
