Is there a way to add a field to all terms in one termbase?

I have an Excel termlist file, and I want to convert it to a sdltb. Also I want all terms in this sdltb have a same note to tell the translator how to use these terms. (Ex. button name)

I know how to do it in MultiTerms one by one, but I don't know if there is a way to add field for all terms in one termbase?
