Locked Slicers After Navigating Using Custom URL Filters in Power BI

Issue: Locked Slicers After Navigating Using Custom URL Filters in Power BI + Default Selection for MEM_COUNTY Slicer

Description: When navigating from a source report to a target report using a custom URL with filters (e.g., ID_NUM eq '5D' and selected MEM_COUNTY values), the slicers in the target report show only the filter values from the URL. This locks the slicers, preventing further filtering or selecting other values.

Additionally, I want the MEM_COUNTY slicer to behave as follows:

• If no county is selected in the URL filter, all counties should be selected by default.

Current Behavior:

• Slicers reflect only the values passed in the URL (e.g., ID_NUM eq '5D' and certain counties).
• Users cannot filter or select additional values within these fields after the URL navigation.
• If no value is selected for MEM_COUNTY, it doesn't default to selecting all counties

Desired Behavior:

• The slicers for ID_NUM and MEM_COUNTY in the target report should show all available values while still applying the URL-based filters.
• The MEM_COUNTY slicer should default to all counties selected when no county is specified in the URL.
• The slicers should remain interactive, allowing further filtering.

Questions:

• How can I allow slicers to show all values while still applying the URL filter context?
• How can I ensure that the MEM_COUNTY slicer defaults to selecting all counties when no county is specified in the URL?
