[O] #+TAGS has some groups with many entries, suppress hotkey assignment

[Jeff Kowalczyk]

I am using a tagging strategy that required some mutually exclusive tag 
groups
to have large numbers of entries. In the example below facilty and customer 
can
be 30-50 entries to start, and grow slowly from there.

#+TAGS: { category: admin(a) development(d)
#+TAGS: { facility: fac1 fac2 fac3 fac4}
#+TAGS: { customer: cust1 cust2 cust3 }
#+TAGS: { billing: billable(b) nonbillable(o) }

This works well in testing, but the hotkey selection UI automatically assigns 
a
character to all entries. After running out of alphanumerics, it moves on to
punctuation and then to unicode characters.

Is there a way to selectively suppress automatic hotkey assignment? If
supressing all automatic hotkey assignment is the only/better option, I would 
be
content to have no hotkeys unless explicitly set with the tag(x) syntax.

Thanks for any suggestions,

Jeff
