I have a use case, i don’t know if its possible in metabase, in case you have large table represented in a dashboard which require a lot of filter
How about adding all the column name as lookup table (column_name, display_name) and then instead of creating filter for each column i will add only 2 filter, first filter drop down list to select column_name, the second filter will be a text.
Example to add the filter selection in sql editor:
SELECT * FROM TABLE
[[ WHERE {{column_name_from_filter_1}} = {{text_from_filter_2}} ]]
