Total Delay Calculation

[srmorris2]

Describe the feature
A total delay time of a button, displayed next to the button number, possibly turned on and off as a setting either in the button or global.

Usecases
When stacking buttons inside a single button (having a button trigger a series of other buttons), delays need to be added up so that they are not all pressed at the same time when they need to follow. If the button delay total was calculated it saves a manual step, OR could be a selectable option when pressing internal buttons.
