Have a column your parts table labelled "notes", and list the notes elsewhere like this:
NOTES:
(General Notes applying to all parts listed)
1.
2.
3.
...
(Specific notes applying only to part numbers as specified in the "NOTES" column in table):
50.
51.
52.
...
Note the clever use of a number break, so you can add/delete from both lists without having to renumber the whole pile. Not that it will help. Note that the preceeding note should not be construed as a drawing note, just a descriptive phrase within this paragraph. As should that one.
Another company I worked at had general notes listed as just numbers, whilst flagnotes (a box-like symbol around the number of the note) applied only to specified parts of the drawing, either indicated by leader lines or adjacent to callouts or table entries.
Probably a thousand ways to skin that cat...
