Love the app etc

Just a quick something that would be most useful to me (maybe others too)
I generally use the FD for general notes and processes in my day to day life and would like to know if there could be an internal linking system actually on the cards themselves?
Lets say I'm learning a process at work - lets say making sandwiches for people to keep things simple

Deck 1 gather main ingredients
get bread
slice bread
butter bread
deck 2 bacon sandwich
get bacon
fry bacon
add sauce
deck 3 cheese sandwich
get cheese
slice cheese
obviously deck 1 is the first instance but a decision has to be made when we reach the end of the card sequence
therefore on the last card could there be dynamic links e.g. bacon / cheese which could be tapped to open that respective deck to allow me to follow the flow of both the learning process and a decision making process
Very basic example I know but we are considering rolling this out in whichever form for our production line staff for basic fault finding on equipment and processes
Thanks for the great app
