can open .ngc file via pyvcp panel?

I have created a pyvcp macro for a specific program named file.ngc. To run it and change its parameters I have to open the file manually using the open menu on linuxcnc. Can I create a shortcut or button on the pyvcp panel to open the .ngc file?

If you want to execute a G-code file on pressing a PyVCP button, then I don't think that PyVCP supports this.
You can do it with G-code subroutines and action buttons in GladeVCP or QTVCP though. linuxcnc.org/docs/html/gui/gladevcp.html...an_o_word_subroutine

However, would just changing the default G-code file to be your G-code rather than the Axis splash screen do what is needed?
