AutoCAD has leaders which consist of an arrow and some multiline text.  The arrow can be bent and its length can be adjusted.

I use these for wire callouts on pages where I cannot draw every individual wire.  I'm trying to find something comparable in Solidworks Electrical 2019.  I've tried custom symbols and blocks, but neither can be adjusted in length or bent like AutoCAD leaders.

Is there a way to make leaders like this in Solidworks Electrical?
