CSV format HB estimation input data for anchored maxdiff

I try to figure out the CSV format HB estimation input data for anchored maxdiff.

Say I have an anchored maxdiff with 10 attributes,  8 cards, and 4 attributes on each card. For a card showing attbs 5, 6, 8, 10, where 5 is the most important and 10 the least important. I code the csv-format HB estimation input for this task as below.

CASEID    Task#    Concept#    Att1    Response
175               1                 1                     10                -1
175               1                 2                      5                 1
175           1                 3                      8                 0
175              1                 4                      6                 0

For the anchor question,  attbs 2, 5, 8,  9 are selected as attbs making this respondent 175 willing to pay extra. How many tasks I need to create for the anchor question? How should I code them?

Are the below two tasks making sense? How should I change them?

175               9                   5            ??                     0
               
For attbs having no impacts

175                10           3               4                     1
175                10           4               6                     1
175                10           5               7                     1
175                10           6             10                     1
175                10           7             ??                     0
