Magma Block to magma cream

Since we can use magma cream to manually craft magma block, I would like to be able to convert magma blocks to cream. When venturing into the nether (especially for the first time) it can be terrifying to collect potion ingredients. Converting magma blocks to cream can be a more efficient way to collect what you need for a fire resistance potion. (And you still need the blaze rods (Blaze powder) to make the potion stand work so having an excess of materials doesn’t hurt anything.)
