Link/reference to symbol

[tolleif]

Problem: I have created a symbol which I'm using many times in my Drawio file, in multiple pages. If it's an embedded image my Drawio file gets very big with redundant data. If I want to change my symbol I have to change it many places.

Solution: A new insertable object that is just a pointer/reference/link to another existing symbol in the same file. Possibly in another page. I.e. "symbol library page"

Examples:
I have a symbol for a valve which I use in a bunch of PI&D drawings. I want to change the valve a bit, but I only want to change the reference symbol, all linked objects immediately display the change.
I have a little company logo symbol which I use in many pages but then the company changes name again. (this can often be solved with background diagram, but not always practical)
I have a JPG/PNG image that's 100kbyte. Suddenly my Drawio file is tens of megabytes big when I re use it often.

For advanced topics, property override on linked objects would be cool. I link to a reference symbol and then a few of them I change the fill color. Ok, getting a bit ahead of myself here, let's start with pebbles. :)

Thank you for your time.

I would like this as well. In my case I have a few composite visuals that are repeated in several different diagrams and may require revisions.

Also, it would be great if I could create these symbols in isolation in, say, another page, and then hot-link them into a larger more complex diagram and have them update dynamically.

Another reason this would be convenient is it would make it easier to export the smaller diagrams in isolation for use elsewhere (like documentation).
