Custom User Defined Symbol in NX 9 (SBF) ?

[biw01]

Hello Everyone,

Is there a way that I can define a custom sbf file and attach different symbols to that file ? I need to use a symbol that I have created at my end, in a text field in 2D. We can only only use (user defined symbols) for such scenarios.
A user defined symbol can be simply referenced using <%SYMBOL_NAME> in the text field.
Please help. I have been struggling to get this working.

Thanks,
Amitabh
