Block properties?

Does LibreCAD have any properties for creating blocks? I often draw drawings with repeating blocks. I really miss the auto-numbering feature in the text block. This is especially useful for electrical schematics, where you need to insert multiple blocks of the same type and assign names like QF1, QF2, QF3, etc. Each block has a unique name and an increasing number. Does LibreCAD have anything similar?

As I understand it, I need a property editor and attribute support for the block.

blocks are supported via Library and Block widgets (just enable them, it necessary).

Actions in block widget allows to create block, edit it and insert into drawing.

However, attributes of blocks (as in AutoCAD) are not supported so far.

Support of block attributes is planned and should be available in one of upcoming updates.
