The work around:
In the prompt's properties add to the Static choices and the Default sections the value 'All'. Next, in the query, there is the original data item that will be presented (leave that alone), add a copy of that data item and call it "Filter_XXX". In the data item's expression definition add a concatenation function and prefix it with 'All'. For example, CONCAT('All', Column1).
Next, edit the existing filter with the following:
SUBSTRING( [Filter_Column1], 1, 3 ) IN (?p_Prompt?)
OR
SUBSTRING( [Filter_Column1], 4 ) IN (?p_Prompt?)
Not exactly the most efficient querying, but so far this is working.
