Record all Random Words from Lists of Letters

Hello!)
I am trying to generate random words from the list of the vowels and the consonants standing in different columns - I am using F9 to recalculate next bunch of the random words but I wish to collect all of them in one single list. Can you please help me do this? In the future I plan adding more columns to the green area shown in the attached worksheet.
Hoping to hear form you soon!)
Thanks!
