[GNC] Bills: can I tag them other than by "Job"?

[Eric Chapman]

I want to tag each bill with something like "2022 Inputs" (inputs are 
seeds, fertilizer, compost, etc.), "Equipment", "Needs 1099", etc. In 
some cases I need to tag bills with more than one tag.

Is there a good way to do that? I see that "Job" can be used to tag a 
Vendor, but I don't know how best to tag bills. I guess I could use some 
prefix on the "Bill ID", but I'd rather have some other field. I guess 
besides "Bill ID", I could use the "Notes" field.
