This is the template I use to fly with the Ka-50 Black Shark. I have a screen under it and I open the .jpgs on each screen, I make a slideshow on each and pause it (spacebar). If you don't have a screen under your MFD Cougar, print the PDF, cut on the red marks and use it.
For the planes with their own DDIs or MFDs, like F/A-18C or the Harrier, the functions are used pressing a Modifier, in my case, the Button 4 on my TM Warthog Hotas Joystick. For the planes without a DDI or MFD, I use direct function and, sometimes, even a modifier to add a second function to the same MFD button. On the Ka-50 case, I use the same MFD button sometimes with double functions using the modifier. The screens under it get the Shkval and ABRIS on it, so I use a PDF above it.
Print in a A-4 format and scale your printer to fit in your MFD Cougar. My printer is an Epson L395. Cut it on the red line and it will be perfect in your MFD.
I will add the MFDs .luas just in case you want it to put it on your C:\Users\'your user name here'\Saved Games\DCS.openbeta\Config\Input\MosquitoFBMkVI\joystick
Good luck and Good Hunting.
