Hello,
Actually, when i want to edit a multiple value like “Verify Element Attribute” | “value”;“02110”;5, that’s opening a popup, and in this popup i can edit the values.
It’ll be faster to can edit the values directly in the “Input” column, without a popup.
And the popup could be opened, if needed, by click on an extra button.
Don’t hesitate to ask if it’s not clear 
Thanks a lot,
CH
