Issue with using SHUTTLE in query where clause

Question

Lets say we have a shuttle control on the page with the following 4 values: apple:orange:peach:berry
Lets say I also have a simple SQL query report on the page and I want to use between 1 and 4 of the aforementioned values as part of an "*IN LIST*" sql operation. For example, if the user has selected only apple and orange from the shuttle, I want my query to be:
select * from some_table where fruit IN ('apple', 'orange');
if however, the user has selected all 4 fruits, the query should then read:
select * from some_table where fruit IN ('apple', 'orange', 'peach', 'berry');
I will add the dilemma that I do not want to convert this query to become a PL/SQL based report. Rather, I want to leave it alone as a SQL Query. My initial attempt was to create a hidden item on the page and use APEX_UTIL.STRING_TO_TABLE with a loop to convert the shuttle data to a comma separated list. This worked great, however when I use the this hidden item in my query, it doesn't work properly. I hope I am explaining this well, but when I populate this hidden item, I will get something like this.
apple,orange
Great. Lets say the hidden item above is called P7_HIDDEN_VALUE (for example). I then try to reference it in my query, and here is the problem:
select * from some_table where fruit IN (:P7_HIDDEN_ITEM)
Do you see the problem. The item resolves itself to be apple,orange, when it really needs the quotes to be *'apple','orange'*
Help!!!!
