Do you mean one technology with all the Galore recipes? If so, I can't really do that in practice, but maybe this is useful; a Factorio command that unlocks all the Galore recipes for the force executing the command:
/c for name, recipe in pairs(game.player.force.recipes) do if string.find(name, "^vgal-") then recipe.enabled = true end end
Why would you like to make it possible to have all the Galore recipes be in a single technology? Maybe I can think of another new feature knowing the reason behind your initial suggestion.
