Duplicate SELECT field options multiple times, with one location to edit

& Contact Form 7 v4.4.1

I have a form with drop-down menu
[select myselection include_blank "class1" "class2" "classAA" "classBB"]

And this selection repeats 10-20 times in a submit form. My form is nothing fancy, just an online form for registering online classes/courses.

Above sample is short but actually there are about 10 options. So, when I go to update classes I could be updating 100-200 “options”.

If my situation makes sense so far, then I was hoping there is a way to enter class options in a single location (easy to edit for me) and then just recall these options in a way that, i.e.

{call-to-insert-options} = include_blank "class1" "class2" "classAA" "classBB"

[select myselection1 {call-to-insert-options} ]
[select myselection2 {call-to-insert-options} ]
[select myselection3 {call-to-insert-options} ]

Thanks for reading.
