Attaching a dimension that shows position

I am very new to both CAD and LibreCad.

Currently I am doing a panel layout for an electronics project. The positions of the panel components (switches, connectors etc) are shown using dimensions from the edges of the panel.

Is there a way to "associate" or "attach" the dimension to the object (switch, meter, connector) so that when it is moved the dimension reflects the change? Or do I have to delete the dimension and re-do it?

There are no "associated" dimensions in LibreCAD.
You can use Tools - Modify - Stretch to move the object, if it can be grabbed isolated. When specifying the selection window also the marker/handle of the dimension extension line is caught and moved along.
Alternatively you also can just select the dimension and move the according handle manually, snap works here.

Stretch does the job, typing in the amount to move by gets to exactly the right point. Thanks
