Duplicate all tracks in a loop Elements 10.5

I made a project by recording from my MP3 player. Now I want to extend the solo sections. I have the locators set and when I activate cycle (the purple button) it sounds correct. So I want to duplicate all the tracks three times and insert them right after the loop, so the solo section will be four times longer. Then I will do this for the two other solo sections.

How do I duplicate all the audio tracks as set by the locators and insert the duplicates right after the locate out point, shifting everything after the out point over the exact amount of time to make room and then continue in time?
