[Feature Request] Switch blocks keeping Data

[Lorrainrm]

Issue:
Changing a lot of blocks with different datas

Solution:
Save a dictionary, so we can just replace certain blocks to a preset block, keeping the block data.

Ex, i need the switch a bunch of acacia blocks (slabs, doubleslabs, fence, fence gates, blocks, from different orientation etc), i want to replace each block to oak, keeping the rotation, data, etc.
I could just checkbox 'keep block data if possible' and let the Amulet replace it

I could also make my own dictionary stating what block will become.
ex: I hate Glazed Terracotta, so i can select an area and switch every White Glazed Terracotta to Quartz Block

This illustrates what i mean:

I'm switching those andeside stairs to quarts stairs
