How to convert table into multilevel list?

[microsoftsloot]

Hi everyone!
I have a table that I would like to covert into a multilevel list (with numbers and letters). The table is structured in such a way that there is a column for the number and a column for the letter corresponding to each line of text. Is there a way I can tell Word to convert the table into the multilevel list while telling it which columns to use for the numbers and letters in the list?
Thanks in advance!
