Hi @TylerR
I apologize, but it is difficult to understand the details of your inquiry at this moment.
May we ask how you have set up the filtering via Javascript query?
If the query refers to a query retrieved with the kintone.app.getQuery function, like below,
const currentQuery = kintone.app.getQuery();
I think it is possible to add the condition to “apply the additional filters added by the user” for the value set in currentQuery and develop it to a newly defined variable such as currentNewQuery, after specifying it in the query, and then execute the “GET” Bulk Record Retrieval method.
Would the above process be feasible for you?
If this is not what you are looking for, please let us know the phenomenon you are having trouble with, what kind of situation you would like to improve, and include the process details.
