Hi @Emil_Stefko,
Yes, you can import a multi-select field both as property and dimension in eazyBI.
If you would like to see how many issues have which kind of combinations, you should import this field as a CSV dimension, see another community post on how to configure the field in such way here: Checklist Unique Combinations - #2 by gerda.zandersone.
The result would be similar to this - there is one issue with the First option only and one issue with the First and Second options (and many with no selection):
