Assigning a find/balloon number at Assembly Model level to reflect at Drawing

I need to make an assembly and drawing based on the customer input drawing with balloons on it. I would like to Assigning a find/balloon number at Assembly Model level to reflect at Drawing .

Conditions: I don’t want a particular part model balloon number to be a file property or system property because I use this part model in several other assemblies where the balloon number is different.

I should be able to assign this balloon number while putting these part models together to make an assembly model (so I don’t have to go to drawing and re assign the balloon numbers)

If found a solution, this is a very time saving/handy for the big assemblies and drawings where you just make a drawing and hit a button asking to bring those balloon numbers assigned at assembly model over the face of the drawing.

Looking for a best possible solution (or any other alternative options).

Thanks
