I have recently had a problem where I wanted to monitor multiple directories but the FileTrigger only supports a single directory. Added to this I also needed to change the Queue the job was listeneing to based on our deployment pipeline. Without a pattern in the Binding I had to duplicate code for each different pattern we needed to support. I have created, currently, four methods for each directory we need to monitor. Allowing patterns in the binding would bring this in line with other triggers I have been using.
