Default Mac File to Open in Parallels App

Hello, I'm setting up my parallels configuration and I have a somewhat unusual filetype (.epl) that is a printer label that can only be opened in a windows application that sends it to my label printer. The application that opens it is actually a batch file that I created in windows. Now if I am inside parallels and I open up the .epl file with my batch application everything works fine and the label is printed. When I try to open my .epl file on the mac side it asks me to choose an application and when I navigate to the batch application I created it does not let me select it (see pic). Any ideas how I can override this so that any .epl files created on my computer, regardless of being in windows or mac, get opened using the batch application I created?

 

[SUB].bat files are executed by cmd.exe, the command-line in Windows, that's the application that has to open up your batch file on Windows.[/SUB]
