revit sampling within a family.

[RudyB1]

Bye to all,
How can I sample within a family without having to resort to a host family of symbols?
I explain better, I have an electrical outlet on the ground and I would like to draw its symbol directly inside the family itself without having to create a family of annotations. .
is it possible to create a sample (e.g. colored) with the lines of symbols (or with any other method)?
Thank you very much." ! ! !

mhm...negative. I'm afraid you have to create an external detail component and upload it to the electrical system family
