Referencing objects in different sheets

I was wondering if there was a more efficient way to reference objects from different sheets.

Currently, I am using a method where I have a column on the left hand side of my sheet:

with sheet number on top and "line" number on the bottom, as as sheet map. So when I have to reference something externally to the current sheet, I place one of those hexagons in the sheet with the corresponding location.

Is there a better, automated way to do this, as this can be frustrating to change when there is a slight shift and the line numbers have to be changed.

Are you looking for some method to automatically change the line numbers?

Have you considered inserting the symbol as an xref?

Can the xref be made to automatically update line numbers if the component is shifted around a sheet?

Not to my knowledge.

I'm not sure there is anything like that for LT or that wouldn't be part of a vertical product. Your choice of program limits your options.
