It's difficult to give a more accurate answer because you aren't giving us anything to work with, such as an example .capx, or a picture of the events you are referring to.
Here is the entry in the manual for Functions: https://www.scirra.com/manual/149/function
Basically, you would add the Function object to your project. Then place whichever events you wish to call in to a new function, then when you need it, you just Call the Function.
If we knew which events you wanted to repeat, this would be much easier to explain, but read the manual entry and you'll see Functions are very easy to use.
