Application Express :: Possible To Avoid Hard-coding Item In Shared Select List Query

I created a "Select List" in the Shared Components area as follows:

My goal is to create a shared select list that can be used on any form for a particular Field.

IF :P10_FK_RSTA_CODE is NULL THEN
RETURN
'select col_description, col_code_pk
from CODE_TABLE
where col_active_ind = ''Y''';
[code].....

Which works great, but how can I make the select list work for the same column on a different form? Because :P10_FK_RSTA_CODE is hard-coded in the function, I can't reuse this Function from a different form. (I could rename the Field on every form to the same name, but I'm hoping there is a better way.)

Is there a way I can pass in a variable from the Field Item to make this dynamic where I can use it on any form?
