Change listbox value

Hello,

I have created a sheet with a rowsource from A1:L19 in sheet1

What i want to do is change the value's in a userform. I have an example of how i like to see it.

But in that case i need to create for every cell a separate textbox. Is there a easier way to manage/change this? I only need to have the buttons edit and change. How can i manage this?
See attached fileChange listbox.xlsm
