By default, creating a one-line diagram generates panel blocks with dynamically sized width to accommodate the number of outgoing connections. This is because the default riser block for panels is set to <Custom Panel Box with Bus>. As a result, a panel that feeds three other panels will have a one-line block three times as wide as a panel which feeds only one panel.

If a user wants to generate one-line diagrams which include a default set of labels, they first have to create a one-line block containing the desired labels from entities in the drawing. However, when the user then changes the default panel one-line block from <Custom Panel Box with Bus> to the one-line block they created, then subsequent one-line diagrams will contain panel blocks which do not resize themselves. This limitation creates messy one-line diagrams when panels feed multiple pieces of equipment.

To address this issue, I propose a set of features that allows the user to define default labels for each equipment type (Panel, Switchboard, Transformer, etc) complete with suffix and prefix settings. This way, the user could leave the default block selection on <Custom Panel Box with Bus> to ensure their blocks are sized correctly while still including the relevant label information.

Ideally any <Custom Panel Box with Bus> blocks also take label text length into consideration when being generated. For example, the voltage label's text length exceeds the default width of a panel with no outgoing connections.
