Block Label Improvements
Block labels and connecting linework now update automatically when items are moved, removed or added. Blocks are associated with their connecting label line at the time of creation and moving the block updates the connection location to match.

A new tool has been added with the command name badd which lets you connect newly placed symbols to an existing labelled array. To use, select the symbols to add (same symbol as existing), then select the array’s label.
Symbols that already belong to the array, or that belong to a different plant, are filtered out; new symbols are connected and the label quantity is updated.
You can also use the trs command to substitute one symbol for another with the new block name updated in the label.
