Customize the starting and stopping point of Timer in Timer Component

[LukeSaward1]

Currently, the timer starts at New Game and stops when the final button is pressed. I want the user to be able to customize this.

A mockup UI could look something like this:

Start on button: true/false
End on button: true/false
Start on cube: true/false
End on cube: true/false
Button to start on: [int input]
Button to end on: [int input]
Cube to start on: [int input]
Cube to end on: [int input]
