How to trigger a user selection for files when creating an automated workflow?

[#1]

I'm attempting a fully automated analysis workflow and have been successful except for one step. When I'm recording and select a file from a file folder to analyze, the workflow records to pull that exact file each time. How do I change the JSL code to prompt the user to select a file manually within the analysis workflow? Or are there other solutions to this I am not thinking of? 

Kindly, 

TK

One way is to change the Open ("directory/to/use/file to open.jmp") section to just say Open (). In the picture below, this means deleting the highlighted text. This will force JMP to ask for a file.
