How to Use Launch Center Pro to Launch a Timer

i'm trying to think about modularity of like don't build a big shortcut to do everything build shortcuts that can call other functions and there's some great tricks about you can use the the pace board on ios as a place to temporarily store a value so you can have one shortcut write a value to the clipboard and then it launches another shortcut which then reads the clipboard and pulls that value in. If you have any experience programming at all it really pays off here because i'm trying to thinking about modularity  and building an action that calls all those many actions is very important.
