NBT tags and random ticking for FLUIDS

I think you should add the possibility to associate NBT tags with fluids as well, i wanted to create a procedure that made my fluid turn into its solid version when the temperature reached a certain level, but in order to do that properly i need a NBT tag that the program won't let me bind to my fluid. Also, you could add the possibily for fluids to tick randomly, just like normal blocks, this way you could create some decorative effects like random particles and things like this.
