Writeable Blocks

[dwarfmaster1974]

Hello survivors,

 

there are writable signs and also writable boxes. 
But it would be wonderful if you could also write on other things, such as plates or all kinds of the arrowHelper's.

My attempts to extend the 'playerSignWood1x1', for example, have unfortunately always failed.

 

Does anyone have an idea or, better still, an example of how something like this could be realized?
