Add Custom Property to Batch Plot options

[PhilSchBell]

Some years ago there were a similar idea "Add Assembly's BOM Item Number to Batch Plot options". Unfortunately the post was archived.

Now we need something similar so it would be nice just to add a field "custom property" so everyone who need a property plotted can fill it on his own.

Would be nice to give us the opportunity to insert a custom Property to the plot Stamp (in our case the state property, so its more easy to see that it is a "for review" drawing or something like this):

There is already the option to use a property as a watermark.
