For best results, use a cone stand. You can make one by cutting holes in a deep, sturdy box.
Place chopped berries, sugar, and rum in a small bowl. Cover and let it sit for 1 hour. Strain, mashing berries gently against the sieve. Save the liquid! Blot the berries thoroughly between paper towels.
Measure ¼ cup of the berry juice into a small cup. Sprinkle with gelatin and let it sit for 3-4 minutes. Transfer gelatin to a small pot and whisk on low heat until mixture is fairly clear. Slowly whisk in ½ cup of berry juice. Stir until warm and all gelatin is dissolved. (Discard remaining juice or use it in a cocktail!) Add the berries and let the gelatin mixture cool and thicken. To speed this up you can put the pan in cold water bath. If you refrigerate it, watch closely; you want it thick, but not set like Jello.
In a small pot or microwave-safe bowl, slowly melt chocolate and coconut oil together. Use the lowest heat and stir often if melting on the stove, or at 15-second increments in the microwave. Stir well!
Drop 1 teaspoon of melted chocolate mixture into each cone. Use a pastry brush or gloved finger to spread evenly inside the cones. Place upright in refrigerator or freezer to harden. Set remaining chocolate mixture aside.
In a large bowl, beat the cream cheese and powdered sugar together until smooth. Stir in the thickened berry mixture.
In a small bowl, whip the cream until stiff peaks form. Fold gently but thoroughly into the cream cheese mixture.
Fill each cone level with the top. Place cones in the freezer. Put the remaining filling in the refrigerator to firm up (at least 1 hour).
Remove cones from the freezer and put a scoop of berry mixture onto each, using a knife if necessary to smooth it down to touch the top of the cone. Return to freezer for an additional hour. (Longer is fine.)
Place chocolate mixture in a large mug or small, deep bowl. (If chocolate has hardened, warm gently, stirring often.) Dip each cone, allowing excess to drip back into bowl before turning upright. Quickly add sprinkles if desired.
Freeze until ready to serve. Each cone may be individually wrapped. Small disposable pastry bags work well for this!
