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.
