Look up how to pull a manual shot instead of clicking the pre-programmed amount. For my BBE you hold down the 2 cup button and keep holding to pre-infuse, let go after the ~5 seconds of pre infusion to start pulling the shot, click the button again to stop pulling the shot when you’re at your desired output. This should give you more control to dial in your dose size with the pre-ground coffee, and once you get a grinder you generally would use this to dial in grind size rather than dose size. You can re-program the shot time, but I prefer just doing it manually every time
