> [@YvetteLans](#): > > I’m wondering if it would be possible to change fields into databases? For example category, author, tags. It’s a bit complicated to make the Author/Category into databases, because the readwise API does not report them as uniquely identifiable entities (just text strings). It’s a shame we don’t have [Single select field options as level in smart folders](https://community.fibery.io/t/single-select-field-options-as-level-in-smart-folders/1844) It is possible to choose whether the field is text or single-select at the time you initially configure the fields (the default is text, but you can choose single-select if you prefer). But I will roll a change to make single-select the default choice for the - author - category - source - highlight color fields. (Tags should automatically default to a multi-select type) --- _[View the full topic](https://community.fibery.io/t/may-18-2023-files-in-documents-images-on-board-view-dynamic-values-in-relation-filters-readwise-integration/4466)._
