Split aggregation for a filter in LookML

[mmaslina-166090]

Is it possble to use something similiar to string_split in LookML to get unique value for my filters?

I have a table that looks like this:

id	Column1	Column2
12	dog, cat	apple, pear
23	dog	cherry, apple
34	cat, deer	cherry

I want to create filter using column1 and column2, but i want this filter to have unique values. For example, the filter for column1 should contain “dog; cat; deer” and no combinations.
