A Macro/Logic Editor Preset to Repeat a Selection 4x with silence between repeats & decrease gain

Hi,

I was wondering if awesome advance cubase users could help me to complete a macro to repeat a Selection with range tool and have 3-second silence between the repeats & decrease gain say for -6 dB each time.

So far I have the macro as:

Transport - Locators to Selection
Edit- Global Copy
Transport - Locate Selection End
Edit- Pate Time
Transport - Locate Selection End
Edit - Pate Time

Any help would be greatly appreciated!
