My current FEL setup has a dual spool valve configuration with 2 levers one for up/down and one for tilt. My question is could I replace that block with a 3 spool/3 lever configuration and use the third lever for my 3rd function for a grapple. Sorry if this is a dumb question but the only 3rd function kits I have dealt with were the electric over hydraulic on a 1 lever setup
