I wonder if I can use an enclosing folder to reduce the number of matches when a workflow uses a file filter. Say, some workflow gets the folder name using a file filter and then open it with some specific application. If I want to open a folder with common name, say "src", it is not possible to specify what I want as almost every folder contains such a subfolder. However, it can be easily narrowed for example if I want to open "~/Downloads/src", in which case I may want to simply type "Downloads/src" to specify it. Is it possible?
