This plugin adds a setting named "Pressure Advance" to the Material category in the Custom print setup of Cura. The plugin inserts a "SET_PRESSURE_ADVANCE" command in the Gcode to set the Pressure Advance Factor for klipper-based printers.
Though it has not been tested, this plugin should work with the "Material Settings" plugin, allowing you to set different pressure advance values for different materials.
The recommended way to install this plugin is via the Cura Marketplace. Just search for "Pressure Advance".
