Add custom text field to spot coordinate family

[spencerm57RLZ]

I'd like to add a custom text field to the spot coordinate family, but it looks like this is not possible. I need to give each spot a unique ID # either above the spot coordinates or below, any ideas on how to achieve this?

Nest a generic annotation family with label (not text) to the spot elevation symbol family.  Be aware that the location of the nested family will be fixed in the project, not drag-able like the spot elevation value itself.  My recommendation is using the built-in prefix or suffix instead of something above or below.

Thanks ToanDN - I was trying to nest an annotation, but because you cannot attach a parameter to an annotation family I added the parameter to the wall or floor families and populated the text field. Nothing showed up in the nested generic annotation ( I checked -the category was turned on in VG). If this is the only way to do it there is one other issue and that is that each coordinate needs a unique ID so adding one ID# to an entire floor would give me the same number each time I added a spot coordinate for that floor. ok, I'll try to get one of the prefix/suffix fields to work
