Okay so i have 7 different containers all asking for seperate files and outputting 7 different outputs, however I'd like it to run any possible combination of the 7, maybe just 1, or 1 and 2, or maybe all 7. However to proceed its making it require an input of all 7. Is there a way i can do a check box or something to choose the combination of the 7(by disabling the containers) I want and then only input the files I need from there? Or would I need to do a chained analytic app which help would definitely be appreciated either way. This is an example of what the 7 containers look like.
