Different Batch Execution depending on input file in RPAS CLOUD

Good Morning all,

In an RPAS Cloud environment, is it possible to execute different batch structures based on whether an input file is found or not?

Basically, if an input file Exception.csv.ovr is found, I need to run batchA, while if the file is not found i need to run batchB.

Based on my understanding, the usage of trigger files will not help me: if I have a trigger file such as exception_trigger.txt, batchA will be executed, while if the trigger is not available, the procedure will stop (the guide says "By default, the waittrigger task waits for 23 hours for the trigger file to appear before timing out and reporting an error."). Am I missing something?
