Any items not available in these areas can be added by creating a **merge query**. ## Creating the merge query 1. Go to **Queries / Reports**. 2. Select **New Query**. 3. Configure the following settings: - **Name:** Enter a name describing what the merge fields are for, like *Reader Dashboard*, or *Custom Application PDF*. - 📝 It is no longer necessary to name this query `Merge`. - **User:** Select a user. Defaults to the current user. - **Sharing:** Leave this unselected for now. - **Folder**: System - **Type:** Configurable Joins - **Category:** Records - **Base:** Application - **System Key**: Merge 4. Select **Save.** 5. Add **Exports** that contain the values that will be used as merge fields on the PDF. 6. Update the export names for the merge fields to be **unique** and **computer friendly:** - Merge fields must be unique among other merge field names on any other Merge or MergePublic query, or any custom or standard field names. - For example, *Application Entry Term* should be renamed `app_entry_term` 7. Select **Run Query**. 8. Confirm exports display the data as it should appear in the Reader. 9. Return to the query overview page. 10. Select **Edit**. 11. Select **Sharing.** ## Adding the merge query to the PDF Editor 1. Go to **Database → Files**. 2. Find your PDF and select **PDF Editor.** 3. Add the [Merge query fields in the PDF Editor](/v1/docs/custom-pdf). The merge fields created in this query can now be mapped in the PDF Editor. 4. In **Field Name,** copy and paste the name of the new merge field. For example, `app_entry_term`.
