How can I update the default symbol set?

[vintly]

I would like to add a triangle to a symbol set which is always available on a new document without having to pull up a saved symbol set every time. I use a specific shape to make patterns for different shaped panels, never the same shape but always the same symbol used. Thanks in advance!

Open the document profile you intend to use from C:\Users\Username\AppData\Roaming\Adobe\Adobe Illustrator 27 Settings\en_GB\x64\New Document Profiles

Add your symbol to its symbols panel. Save the file.

Thank you, that's a viable fix, appreciated. Means I have to select a profile in the new Document window, which is ok, but if it's possible to have the symbol present in the non-selected (Custom) profile that would be great too.

Every document is based on a document profile. 'Custom' is just a document profile that you have modified the settings of.

It's all good, working a treat now thank you!
